Brooklyn-based hardcore metal band Biohazard has reunited with all original members and will play May 9th in Seattle. The band also has three dates scheduled in South America. The band was joined on stage by Sen Dog of Cypress Hill on March 28, 2009 during their show at the newly renovated Hollywood Palladium in Los Angeles, California (also featuring Suicidal Tendencies). In addition to playing their 1994 collaboration "How It Is", they also did a version of the Cypress Hill song "Ain't Going Out Like That", which then went straight into a cover of Public Enemy's "Bring The Noize".
