The Definitive Part One, released in 2008, is a compilation album by the British heavy metal band Cloven Hoof. Apart from one new song, "Mutilator", all of the tracks are re-recorded versions of existing Cloven Hoof songs from the past. The drums, bass, keyboard and rhythm guitar tracks were recorded live in the studio, with vocals and guitar solos being dubbed in for a cleaner finish. Guitarist/keyboardist Mick Powell was still a part of the band's lineup when this album was recorded, but had left by the time of release and is credited as a guest musician.
