FETISH ATTIRE MANDATORY BOUND kicks off spring with an absolutely careening lineup. RUIZ OSC1 returns to the room for a headlining set. No one hits quite like she does - RUIZ OSC1 specializes in high-bpm “folkloric groove techno” that draws on the music of her native Colombia, fusing it with elements of hardgroove, rave and classic techno. Releases on Héctor Oaks’ KAOZ have shown her in riotous command of her craft as a producer, pushing searing velocities with a deft hand. Concrete Husband summons a dark power with absolute impunity. His background in classical music is evident only in his exquisite compositional control, but there’s not a conservative drop in Concrete Husband’s music. “I toy with the pulse of your heart / because I just want to fucking tear you apart” he intones on the recent “Your Pulse,” warping his voice to demonic effect. You’ve been warned. Resident, organizer, visionary: Katie Rex completes the lineup. Rex has, without any caveats or qualifications, been one of NYC’s most essential musical and curatorial voices of the last decade, and her artistic evolution continues without fail. A fearless DJ with an absolutely wicked flair for the powerful, Rex brings it home every time. NIKS makes her debut. The London-based artist is a driving force behind Black Artists Database, the sprawling community-based platform & catalogue of Black musicians that has now evolved into a label. In her own productions, NIKS embraces a flowy but urgent sound that is perfectly in step with some of the most classic ‘90s house, without being overshadowed by her influences. Tracks like “Mimi’s Woo” and “V2B” transmute tribal house through a 2020s sensibility and feel in conversation with genres as varied as modern bass, neo-rave and more without any overt reference. Simply put, NIKS is bringing heat. Kim Anh continues to steer STUDIO into shadowy waters. The NY producer owes a clear debt to the synthiest side of the ‘80s, with tracks that betray no small familiarity with the back catalogue of Mute Records, the work of Liaisons Dangereuses and early Trax Records. Yet in her loving hands, these foundational sounds find new fluidity. Chalk it up to Anh’s own artistic conviction; she pours her whole self into her productions, and the result is something that feels utterly personal. Miss/chief collective member Kfeelz basks in dance music’s most timeless pleasures. Luscious vocal house, jazzy flourishes and heavily swung percussion are all present and accounted for; her mixing is defined by a throughline of pure soul.
