Faith No More covered Black Sabbath’s "War Pigs" on their album "The Real Thing". The song was written by bassist Geezer Butler, guitarist Tony Iommi, vocalist Ozzy Osbourne and drummer Bill Ward, and first appeared on Black Sabbath’s 1970 album "Paranoid".
Faith No More recorded its version during the sessions surrounding "The Real Thing", their 1989 breakthrough album. On the original cassette and some editions it appeared as a bonus track; it became more widely available on the album’s CD release. The cover showed the band’s ability to combine heavy metal with their broader alternative-rock, funk and experimental style.
A frequent mix-up is "Easy", Faith No More’s better-known cover from a later period. "Easy" is a Commodores song and was associated with the 1992 album "Angel Dust", whereas "War Pigs" is the Black Sabbath cover connected to "The Real Thing". Faith No More also performed the Sabbath song live before and after the album’s release.
