Setting the Stage with Sound

When Banana Fish first gripped audiences through Akimi Yoshida’s manga and later the 2018 MAPPA anime adaptation, it did more than deliver a harrowing crime saga set in the underbelly of New York City. The series carved out a distinct sensory identity, and a cornerstone of that identity is its deliberate, emotionally charged use of music. From howling electric guitars to slow-burning blues riffs, the narrative soundscape isn't mere atmospheric filler. It functions as a parallel storyteller, articulating the pain, rebellion, and fragile hope that words alone cannot carry. The show’s creators understood that a story about street gangs, systemic corruption, and impossible bonds demanded a score that could breathe the same grit as the streets Ash Lynx walks. The result is a masterclass in blending blues and rock traditions to deepen every emotional beat.

The sonic world of Banana Fish draws heavily from American roots music, particularly the blues and rock that erupted from mid-20th-century counterculture. This choice is no accident. The narrative is steeped in the legacy of Jimi Hendrix, Janis Joplin, and The Rolling Stones—artists whose music represented raw emotion, defiance, and a search for freedom. By weaving these genres into the fabric of the series, the creators anchor the story in a cultural moment that mirrors Ash’s own struggle: a battle against oppressive systems, a cry for identity, and a soul weighed down by trauma. Understanding how these influences operate within the show reveals why the score feels so visceral and why the audience’s connection to the characters remains so intense.

The Sonic Identity of Banana Fish

Any discussion of music in Banana Fish must start with the atmosphere the series builds. The New York City of the story is a place of neon-drenched danger, back-alley conspiracies, and fleeting tenderness. The soundtrack doesn’t just accompany this world; it constructs it. The show’s composer, Shinichi Osawa (Mondo Grosso), combined electronic textures with live instrumentation to create a hybrid that pulls the listener into a liminal space between the 1980s setting and the timeless rush of urban despair. While Osawa’s electronica forms the backbone, the prominent blues and rock elements give the score its teeth.

Blues, with its 12-bar structures and bent notes, conveys a sense of mournful inevitability. Rock, with its distorted power chords and driving beats, injects adrenaline and defiance. The juxtaposition of these two genres mirrors the duality of Ash Lynx himself: a young man who is both a coldly efficient gang leader and a deeply wounded child. The music doesn’t simply signal emotion; it becomes the emotion. When a slow blues lick creeps into a scene, it hints at old wounds that time cannot heal. When a rock crescendo erupts during a chase or a moment of resolution, it channels the raw will to survive against impossible odds. This dual approach gives the series aural consistency while allowing individual moments to land with devastating precision.

How Blues Echoes Through the Narrative

Blues music, born from African American suffering and resilience, has always been the language of unspoken pain. Banana Fish taps into this tradition to give voice to its characters’ internal landscapes. Ash, burdened by childhood sexual abuse and a life of violence, rarely articulates his emotional state. Instead, the soundtrack speaks for him. Several key scenes employ slide guitar, sparse bass lines, and unhurried percussive clicks that evoke the meditative ache of Delta blues. The guitar wails in a way that no monologue ever could, turning moments of silence into screams.

Consider the moments after Ash reads the coded note about his brother Griffin’s fate, or the quiet scenes where Eiji Okumura tends to his wounds. The background music often strips down to a single blues guitar, its notes bending beneath the weight of remembered trauma. These passages recall the playing of B.B. King or early Eric Clapton—artists whose work the series explicitly references. The result is a soundscape that honors the genre’s roots: the acknowledgment that suffering is both personal and universal. In a 2019 interview Shinichi Osawa explained that he wanted the music to "feel like a wound that won’t close," and the blues idiom achieves exactly that. The unresolved harmonic tension mirrors Ash’s inability to escape his past, turning the series into a prolonged musical elegy.

Blues also underscores the theme of disillusionment. When Ash’s plans crumble and his trust in allies is betrayed, the soundtrack retreats into minor-key despair. The absence of flashy production allows the sadness to sit uncomfortably, refusing to offer easy catharsis. This is the sound of a world where justice is rare and love is fragile. By leaning into the genre’s stoicism, Banana Fish avoids melodrama and instead delivers authenticity that resonates deeply with an audience tired of sugary resolutions.

Rock as the Soundtrack to Rebellion and Resilience

If blues is the series’ trembling heart, rock is its clenched fist. The uptempo tracks that punctuate major confrontations draw from classic hard rock, punk, and even garage revival. Overdriven guitars, propulsive drum fills, and snarling bass lines transform scenes of escape or retaliation into visceral releases. The music echoes the rebellious spirit of the late ’60s and ’70s—a time when rock was the voice of youth pushing back against institutional rot. Ash’s war against the mafia don Dino Golzine and the corrupt network that preys on children is framed in these terms, making the sound a political statement as much as an emotional one.

One of the most memorable uses of rock comes during the prison break arc, where the soundtrack surges with frantic energy. The distorted riffs and relentless tempo match the physical brutality on screen while simultaneously conveying a refusal to submit. Rock’s loudness becomes a symbol of visibility: refusing to be silenced, refusing to be invisible. Similarly, when Eiji’s presence gives Ash the strength to keep fighting, the music often swells into anthemic territory, with clean guitar leads that recall the hopeful side of classic rock. The contrast between the crushing weight of blues and the liberating rush of rock reflects the characters’ oscillation between despair and determination.

The series further cements this connection by naming characters and concepts after rock icons. Ash Lynx’s very name is a composite of two wild animals, but his soul is that of a rock frontman. The show doesn’t shy away from explicit nods: characters discuss Hendrix’s version of “All Along the Watchtower,” and Janis Joplin’s raw vocal style is mentioned as a touchstone for emotional honesty. These references aren’t superficial name-drops; they serve as shorthand for a whole philosophy of self-expression. When Ash picks up a gun, he is also picking up the legacy of those who screamed into microphones and smashed guitars against a world that wanted them broken. That thematic layer is fully realized through the show’s original score and needle drops.

Musical Motifs and Character Themes

Great narrative music creates identifiable motifs that evolve alongside characters. Banana Fish employs this technique to give each central figure a distinct sonic fingerprint. Ash’s motif is a fusion of bluesy ache and rock aggression—often introduced with a clean, reverb-heavy guitar that morphs into distortion during moments of crisis. This duality captures his shifting identities: the brilliant strategist, the vulnerable lover, the relentless avenger. As the series progresses, the motif darkens, with the blues elements growing more prominent as the toll of his journey becomes undeniable.

Eiji’s thematic material leans away from outright rock and blues into gentler, more melodic territory, yet it still converses with the same sonic palette. His scenes with Ash often feature interlocking guitar lines that suggest harmony and the possibility of peace. When tragedy strikes, those same themes are reprised in a minor key, with a bluesy bent that ties his suffering to Ash’s. The interweaving of these motifs creates a musical dialogue that mirrors the deepening bond between the two leads. This technique was analyzed in a Crunchyroll feature on the series, which highlighted how recurring musical cues act as emotional anchors for the viewer.

Even secondary characters receive treatment that reinforces their roles. Sing’s brash confidence is scored with upbeat, punk-inflected rhythms, while Yut-Lung’s calculated cruelty is accompanied by eerie, reverb-soaked guitar echoes that carry a blues undertone of bitterness. By assigning these aural signatures, the soundtrack deepens the audience’s understanding without needing extra dialogue. The result is a narrative that feels fully integrated, where sound and story move as one.

Real-World Musical References Embedded in the Story

Beyond the original score, Banana Fish is saturated with direct references to rock and blues history, functioning as a love letter to the music that defined a generation. Ash’s favorite book, “A Perfect Day for Bananafish” by J.D. Salinger, gives the series its title, but the cultural touchstones don’t stop at literature. Early in the story, Ash is shown with posters of Jimi Hendrix and Janis Joplin plastered on his walls. He name-drops Eric Clapton and other blues-rock pioneers during conversations, using music as a code for understanding the world. These aren’t just decorative details; they inform his entire worldview.

For Ash, rock and blues represent a time when artists told unvarnished truths, challenged authority, and wore their brokenness as a badge. This perception becomes a lens through which he interprets his own suffering and his fight against the system. When he quotes Hendrix or muses on the raw honesty of Joplin’s vocal cracks, he is articulating a philosophy: that authenticity is the only weapon against a world of lies. The series’ reliance on this musical canon gives it a timeless quality and invites viewers fluent in the genre to experience a deeper layer of meaning. A critical essay on Anime Feminist explores how these references frame Ash’s gender expression and trauma through the iconography of tragic rock musicians, adding yet another interpretive dimension.

Moreover, the manga, which debuted in 1985, was already steeped in nostalgia for the late ’60s and ’70s, creating a cultural feedback loop. The anime adaptation, arriving decades later, respects and amplifies this nostalgia, using the soundtrack to bridge the gap between the original setting and a modern audience. This intertextual richness rewards repeat viewing and makes the music an integral part of the plot rather than mere embellishment.

The Anime’s Soundtrack Composition and Licensed Selections

The task of translating Banana Fish’s musical soul into a contemporary anime fell to Shinichi Osawa, a producer and composer known for blending electronic and organic sounds. In crafting the score, Osawa deliberately avoided a purely orchestral approach, instead building a sound that could sit comfortably alongside the classic rock records the characters worship. He assembled a team of session musicians to record live drums, bass, and guitar, ensuring the rock and blues components felt tactile and immediate. The result was an eclectic mix of atmospheric electronic tracks and muscular, riff-driven pieces that could shift from introspective blues to full-throttle rock within a single scene.

The opening and ending themes further cemented the rock ethos. The first ending, “Prayer X” by King Gnu, became an instant anthem for the fandom. Its brooding verses and explosive chorus encapsulate the series’ emotional extremes. Frontman Daiki Tsuneta’s anguished vocals and the band’s fusion of rock, pop, and jazz align perfectly with the show’s tone. The song’s lyrics, which speak of unhealed scars and desperate prayers, act as an extension of Ash’s inner monologue. Later themes continued the trend, with Survive Said The Prophet’s “found & lost” delivering a high-energy rock assault that matched the escalating stakes.

Insert songs were chosen with equal care. While the original soundtrack carries the bulk of the narrative weight, a few key moments feature licensed tracks that reinforce the blues-rock aesthetic. These selections feel less like commercial tie-ins and more like pieces of the world the characters inhabit. In a review of the series premiere, critics noted how the music immediately established a sense of place, grounding the anime in a specific American cultural landscape despite being a Japanese production. The meticulous attention to musical detail demonstrates how seriously the creative team took the show’s sonic identity.

How Music Deepens Audience Engagement

Anyone who has watched the series can attest to the fact that its music lingers long after the credits roll. This is not accidental. Blues and rock are genres built on repetition and emotional release; their structures create expectation and then either fulfill or subvert it. The Banana Fish soundtrack exploits these mechanisms to keep viewers emotionally invested. A slow-burning blues progression can build tension over an entire episode, only to explode into a rock climax at the critical moment, delivering a cathartic punch that feels both earned and overwhelming.

Psychological research on music and memory suggests that strong emotional associations are formed when aural stimuli coincide with peak narrative events. The show repeatedly pairs its most devastating scenes with the most poignant musical statements, creating indelible recollections. When the final episode’s haunting refrain played over images of a certain character, the worldwide outpouring of grief on social media was inseparable from the music that accompanied it. Viewers weren’t just reacting to the plot; they were reliving the sound of heartbreak. The universality of blues and rock—genres that have long been associated with processing loss—allowed the audience to project their own feelings onto the story, making the experience deeply personal.

This engagement extends beyond passive viewing. Fans have created extensive playlists, lyrical analyses, and guitar cover videos, all testament to the soundtrack’s impact. The music doesn’t stay in the background; it becomes a companion to the audience’s own lives. This phenomenon mirrors the way the characters themselves rely on music to survive. For Ash, a song by Janis Joplin is a lifeline. For the viewer, the score becomes a similar emotional anchor. The boundary between fiction and reality blurs, and the narrative soundscape of Banana Fish achieves its ultimate goal: to make the audience feel less alone in their own pain.

The Lasting Impact of Banana Fish’s Musical Approach

In an industry where anime soundtracks can often feel interchangeable, Banana Fish stands apart. Its commitment to grounding the score in the specific cultural resonances of blues and rock gives the series a weight that transcends typical genre fare. Critics have praised the audio design for its narrative intelligence, and the soundtrack continues to be a reference point in discussions about effective music direction. By refusing to treat music as an afterthought, the creative team modeled how a show can communicate theme and character development purely through sound.

The series has inspired other anime to take similar risks with genre-specific scoring, though few have replicated the coherence achieved here. What makes the approach so successful is its deep integration with the story’s text: the music isn’t a separate layer but a main character in its own right. Ash’s journey, with all its impossible violence and fleeting tenderness, sounds like a lost blues record—and that is exactly the point. From the opening guitar wail to the final fading chord, the series wraps the audience in a sonic embrace that is as unflinching as it is beautiful.

Ultimately, Banana Fish proves that when a story reaches into the guts of human experience, the music needs to meet it there. Blues and rock, with their long history of staring into the abyss and refusing to look away, provide the perfect vocabulary. The series doesn’t just incorporate these genres; it lets them speak, and what they say is something no amount of exposition could convey. For those who have let the soundtrack sink into their bones, the sound of Banana Fish will forever be the sound of resilience echoing in an unjust world.
