Biohazard

Biohazard is an American hardcore band formed in Brooklyn, New York City, in 1987. They are one of the earliest bands to fuse hardcore punk and heavy metal with elements of hip hop. The original lineup consisted of bassist/vocalist Evan Seinfeld, guitarist Bobby Hambel, and drummer Anthony Meo. Guitarist/vocalist Billy Graziadei joined soon after, and drummer Danny Schuler replaced Meo before the recording of their first album, thus solidifying the band's lineup from 1988 to 1995.

After several lineup changes, a breakup, a 2008 reunion, and a seven-year period of inactivity, the classic lineup of Seinfeld, Graziadei, Hambel, and Schuler reunited in 2022 and began performing again in 2023.
