Black Sabbath released the 1970 album Paranoid, including “War Pigs” and “Iron Man.”
The album was recorded by vocalist Ozzy Osbourne, guitarist Tony Iommi, bassist Geezer Butler, and drummer Bill Ward. Its heavy guitar riffs, dark themes, and forceful rhythm section helped establish the sound that became associated with heavy metal.
Paranoid was Black Sabbath’s second studio album. It was released in the United Kingdom in October 1970, after the band’s debut earlier that year. The title track became one of the group’s best-known songs, while “War Pigs” and “Iron Man” became staples of classic-metal radio and live performance.
The album is sometimes confused with Black Sabbath’s self-titled debut because both were released in 1970. Paranoid, however, is the record containing the specific trio of songs named in the question and became the band’s breakthrough release.
