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. Their earlier style was technical thrash metal, but the band later experimented with alternative and groove metal elements on their fourth album Green. The band's name was shortened to Forbidden in order to prevent the band from being mistakenly perceived as a black metal band. Forbidden Evil, the band's debut album, was released in 1988.
