Biohazard came together in 1987 and is now recognized as one of the earliest groups to fuse hardcore metal, punk, and rap/hip-hop. The four-piece line-up of Evan Seinfeld (vocals/bass), Billy Graziadei (vocals/guitar), Bobby Hambel (guitar), and Danny Schuler (drums) recorded Biohazard's self-titled debut in 1990 for the Magnetic Air label, introducing their hard-hitting sound with lyrics reflecting their experiences with gangs, drugs, and violence.
Soon after, they relocated to major label Roadrunner for 1992's Urban Discipline. Produced by the band and Wharton Tiers, the album delivered Biohazard a major breakthrough. “Punishment” (inspired by the Marvel Comics character The Punisher and the 1989 film adaptation) yielded a popular music video that became the most-played title on MTV's Headbanger's Ball. The album, featuring original songs as well as a cover of Bad Religion's “We're Only Gonna Die (From Our Own Arrogance),” went on to sell over one million copies.
This 30th anniversary edition of Urban Discipline includes deluxe packaging and an exclusive poster. It also features bonus tracks making their debut on vinyl.
