Which British heavy metal band released the album 'Paranoid' in 1970?

Black Sabbath released the album Paranoid in 1970. It was the British heavy metal band’s second studio album and became one of the most influential records in the history of heavy metal.

The album was recorded in June 1970 at Regent Sound and Island Studios in London, only a few months after the band’s debut. Its lineup featured Ozzy Osbourne on vocals, Tony Iommi on guitar, Geezer Butler on bass, and Bill Ward on drums. The record includes signature songs such as “War Pigs,” “Paranoid,” “Iron Man,” and “Hand of Doom.”

Paranoid was released in the United Kingdom on September 18, 1970, by Vertigo Records. Its American release followed on January 7, 1971, through Warner Bros. The title track was written quickly as an extra song when the band needed more material, yet it became their best-known single and reached number four in the United Kingdom.

The main potential confusion is the album’s release timing in the United States: although it is a 1970 album, American listeners received it in 1971. Judas Priest, Deep Purple, and Led Zeppelin were also British rock or metal acts, but none released this album.
