Genocide is a 2000 Judas Priest compilation consisting of their first two albums, Rocka Rolla and Sad Wings of Destiny, plus a bonus track from the Sad Wings of Destiny sessions as well. Like several others in the past, Genocide was released under the label Gull, in an effort to "capitalize on Judas Priest's popularity." Judas Priest's management firmly states that people should not buy these compilations, because even though it would seem like a new album on the surface, it's just a re-issue of material already recorded.
