The album was well received by both critics and fans and eventually became a cult classic.

[citation needed] Forbidden Evil was produced by Doug Caldwell and John Cuniberti, best known for working with Joe Satriani, at Alpha & Omega Recording, Studio 245 (both located in San Francisco) and Prairie Sun Recording in Cotati.

The album features future Slayer drummer Paul Bostaph and three of the songs were co-written by Robb Flynn, who later played with Vio-lence and Machine Head – although he never played on the album.

He was replaced by Tim Calvert, who would remain with the band until their breakup in 1997.

The title track was covered by Temple of Blood on their 2008 release Overlord.
