Twisted into Form is the second album from San Francisco, California thrash metal band, Forbidden. It features one line-up change from their debut – 1988's Forbidden Evil – with Tim Calvert replacing Glen Alvelais on guitar. The result is a more melodic and progressive affair with many acoustic interludes and clearer production, but less of a raw edge than its predecessor. It is their last album with drummer Paul Bostaph before he joined Slayer in 1992 when Forbidden was on hiatus.
