New Rochelle, New York's Sinicyst emerged in 2023 fusing the dirty stomp of sludge metal, crossover thrash's hardcore bite, and groove metal's rhythmic punch into an uncompromising hybrid that feels like it was forged somewhere between the Westchester suburbs and downtown Manhattan's rougher-edged clubs. Their willingness to blend three distinct heavy subgenres makes for an unpredictable and abrasive listen.
