Biohazard is a hardcore band from Brooklyn, New York, formed in 1987. Known for blending hardcore punk and heavy metal with hip hop influences, Biohazard helped pioneer a unique crossover sound. The core lineup—Evan Seinfeld, Billy Graziadei, Bobby Hambel, and Danny Schuler—defined their early years and most popular era. After various lineup changes, a breakup, and a period of inactivity, the classic members reunited in 2022, returning to live performances and reigniting their impact on the hardcore scene.
