With Sounds From The S.P.E.A.K.E.R. System, Bios Contrast & Nilotpal Das abruptly change course from the expansive drone works of Meltwater Pulse (2023) and Dragon Rising (2022). The album arrives in violent bursts, assembled from Bangla rap, digital hardcore, dek bass, ambient electronics, and an unusually large network of collaborators stretching from Kolkata to Europe and East Asia. Its premise—a world descending into collective psychosis during the Kali Yuga, inspired in part by Das’s own experience of Schizophrenia Spectrum Disorder—could easily have become an exercise in conceptual excess. Instead, organised chaos is built into the record itself. The constant collision of genres, collaborators, and production techniques refuses to settle into a single musical language.
From the opening “Schizophrenic Intro”, the listener is thrown into a vortex of slowed-down, sped-up, looped, reversed, and glitched material, with no attempt to ease the transition. The abrasive momentum of “Gondho Jhaater Chule” barely relents in “Escape”, whose spectral vocals provide only the briefest moment of respite before “Iron Age Fantasies” introduces melodic gestures recalling classic Tollywood soundtracks, immediately distorting them into something deeply uncanny. “Laurar Baal” and “Laura Chos” push the collision between noise, Bengali rap, and sampled film dialogue to breaking point, while “E.M.P.” suspends the album inside an extended electronic blackout, one of its most absorbing passages. The unexpected arrival of the Korean gayageum and daegeum (the former a traditional twelve-string plucked zither with a wooden resonating chamber, the latter a large transverse bamboo flute known for its resonant, buzzing tone) on “Cappucc1n0” offers neither resolution nor sentimentality, but a fragile interruption before “Radio Paranoia” and “Maniac Outro” complete the descent into sonic disintegration.
The use of crude sexual slang and bodily imagery—particularly in “Gondho Jhaater Chule”, “Laurar Baal”, and “Laura Chos”—adds another layer of instability, grounding the album’s apocalyptic vision in the language of the street as much as in mythology. Vulgarity and transcendence coexist throughout the record, collapsing distinctions between the sacred and the profane with the same ease that it moves between Bangla bass, digital hardcore, ambient electronics, and noise.
The density of the album can feel overwhelming at times, and it continually rewires expectations. Yet every stylistic shift destabilises the previous one without feeling arbitrary, reflecting Das’s conception of schizophrenia not as a metaphor but as a lived condition in which disparate realities coexist simultaneously. The album’s many collaborators are given considerable freedom, yet the result never fragments into disconnected contributions; instead, their contrasting vocabularies reinforce the instability at the heart of the project. Challenging but consistently rewarding, Sounds From The S.P.E.A.K.E.R. System places the listener inside the eye of its own sonic vortex, where overload becomes its organising principle rather than an obstacle to it.

Your earlier releases as Bios Contrast—from Dragon Rising and Meltwater Pulse to the forthcoming twelve-hour harmonium drone project under your own name—often revolved around expansive historical, geological, or spiritual concepts explored through long-form composition.
Sounds From The S.P.E.A.K.E.R. System, by contrast, is fragmented, densely collaborative, and rooted in digital hardcore, Bangla rap, experimental electronics, and what you describe as “Brahmancore.”
What drew you toward this radically different format? Do you see the album as a departure from your earlier practice, or simply another way of pursuing the same fascination with large-scale conceptual worlds?
Sounds From The S.P.E.A.K.E.R. System is a very personal album. At the same time, it is a pursuit of a large-scale conceptual world. I wouldn’t say the theme of the album is conceptual, but rather very real. I suffer from Schizophrenia Spectrum Disorder, so it’s a take on my worldview. Everything is random and unnecessary but, at the same time, needed, just like the world we live in. People would call me crazy, but I really felt the presence of something godlike, something that controls all of us humans.
The album imagines a world descending into mass psychosis during the Kali Yuga, with schizophrenia functioning as both narrative device and sonic metaphor. At the same time, it brings together artists from very different musical and geographical backgrounds—BROOD, Kush Arora, Kim Hae Kyung, Ellery Everet, Seraphim, enesai, P.U.S.Y.E.T.E.R., and many others. How did you coordinate such a diverse group of collaborators while maintaining a coherent dramatic arc? Did each artist respond to a specific chapter in the narrative, or were they encouraged to reinterpret the concept through their own musical language?
I didn’t make this album to express or present a very linear story. Every collaborator was free to interpret the concept in their own way. The record is schizophrenic in the sense that it collages many different sounds and genres while maintaining its central theme, which is chaos. And chaos happens naturally while collaborating. At first, I put out an open call for collaborators on Instagram. Many artists quickly DM’d me, and we started a group where we exchanged stems and sounds.
Throughout your work you’ve often spoken about “curating sounds” rather than creating something entirely new, drawing on traditional instruments, field recordings, sampling, improvisation, and careful research. On Sounds From The S.P.E.A.K.E.R. System, that curatorial approach seems to expand into an entire network of voices, genres, and production methods, from Bangla rap and digital hardcore to ambient passages and Korean traditional instruments. Did working with so many collaborators change your understanding of authorship? At what point does a project of this scale stop feeling like an individual album and become a collective sound world?
I started this project with the intention of creating the most mainstream, non-experimental trash music imaginable. The result, however, is the most experimental music I’ve worked on so far. I wasn’t controlling the direction the project was taking; it was a collaborative effort, and it still is. Sounds From The S.P.E.A.K.E.R. System is also the result of a video game that Kim Hae Kyung is currently developing, called The S.P.E.A.K.E.R. System.
In an earlier interview you described Kolkata as having only a small experimental music community, while also expressing admiration for artists working across South Asia. Since then, you’ve collaborated with musicians from Europe, North America, East Asia, and beyond, building an unusually international artistic network. Has making Sounds From The S.P.E.A.K.E.R. System changed your perspective on where your music belongs? Do you feel part of a global experimental community now, and how has continuing to work from Kolkata shaped the way you approach collaboration and the exchange of ideas?
I would say I don’t belong to an experimental community anymore, but rather to a community that spans many genres, so I fit in with everyone. I like all kinds of music. Kolkata has always had a small experimental community, so I’ve simply accepted that and moved on to other communities. I like mainstream, hard-hitting music now—if the music goes hard, I’m all in, regardless of genre. I have a lot of connections with international artists, and I feel I belong to a global community rather than just a local one, because collaborating is fun, and collaborating with people who have totally different ideas and perspectives is even more fun.
