Biohazard is an American hardcore band formed in Brooklyn, New York, in 1987. They are acknowledged as one of the earliest bands to fuse metal, hardcore, and elements of hip-hop. The earliest lineup consisted of bassist-vocalist Evan Seinfeld, guitarist Bobby Hambel, and drummer Anthony Meo. Guitarist-vocalist Billy Graziadei joined soon after, changing the band to a four-piece. Since 2016, the lineup has consisted of Graziadei, Hambel, and Danny Schuler.
