Forbidden was a thrash metal band from the San Francisco Bay Area. Formed in 1985 as Forbidden Evil, the group was founded by Russ Anderson and Craig Locicero, who were both ever-present members. Since their formation, Forbidden have broken up and reformed twice with numerous line-up changes. The most recent line-up of the band comprised Anderson (vocals), Locicero (guitar), Matt Camacho (bass), Steve Smyth (guitar) and Sasha Horn (drums). Along with Death Angel, Vio-lence, Defiance, Testament and Exodus (the latter of the two had featured original Forbidden drummer Paul Bostaph), they were one of the most successful Bay Area thrash metal bands and earned a loyal fanbase in the underground music community and critical acclaim, with their debut album Forbidden Evil (1988) regarded by critics as a classic thrash metal album and the follow-up, Twisted Into Form, as something of a masterpiece within the tech-thrash genre. Their earlier style was technical thrash metal, but the band later experimented with alternative and groove metal elements on their fourth album Green (1997).
