Kosain makes dark, heavy midtempo and bass music for fans of Rezz, Deathpact and 1788-L.

Kosain is a midtempo and bass music producer and DJ based in the NYC area, building a dark, hypnotic sound in the lane of Rezz, Deathpact and 1788-L. Heavy low end and eerie atmosphere sit at the center of everything he makes.
Since late 2025 he has released a steady run of singles, including “Decapitate,” “MESMERIZE” and “PLAY,” alongside remixes and DJ edits of artists like Madeon, Slayyyter and Skrillex that have become some of his most-played tracks. In October 2026 he teamed up with NYC bass artist CMPLXTY on “Nightmare,” the release that took him from single-digit monthly listeners on Spotify to more than 700.
Next up is a busy stretch. “Dreams” makes its return on November 20 with new artwork, followed by the single “ANNIHILATE” on January 8. The ANNIHILATE EP then lands March 19 with four tracks: “ANNIHILATE,” “MOMENTUM,” “CORRUPTION” and “IMPULSE.”
Behind the decks, Kosain plays the Open Decks nights at SILO in Brooklyn and shares freestyle DJ sets on SoundCloud, mixing his own material with the dark bass music he loves.
