Faith No More (sometimes abbreviated as FNM) is an American rock band from San Francisco, California, formed in 1979. Before settling on their current name in 1982, the band performed under the names Sharp Young Men and later Faith No Man. Bassist Billy Gould and drummer Mike Bordin are the longest remaining members of the band, having been involved with Faith No More since its inception.

Chuck Mosley was replaced with singer Mike Patton in 1988. Patton, who was singing with his high school band, Mr. Bungle, was recruited at Martin's suggestion after he heard a demo of Mr. Bungle. According to Patton, he first met the band during a 1986 gig at "a pizza parlour" in his hometown of Eureka, California. Two weeks after joining Faith No More, he had written all the lyrics for the songs that would make up the Grammy award-nominated The Real Thing.  "Epic" was released in January 1990 and was a top 10 hit. The music video for "Epic" received extensive airplay on MTV in 1990, despite anger from animal rights activists for a slow motion shot of a fish flopping out of water. That same year, Faith No More performed at the 1990 MTV Video Music Awards (September 6) and on the 293rd episode of Saturday Night Live (December 1) "From Out of Nowhere" and "Falling to Pieces" saw releases as singles, and a cover of Black Sabbath's "War Pigs" was also produced for non-vinyl releases. In 1990, the band went on an extensive US tour, sending The Real Thing to Platinum status in Canada, the US, and South America. The album also had big sales numbers in Australia, UK, and the rest of Europe, pushing the total sales well above 4 million worldwide.  In February 1991, Faith No More released their only official live album, Live at the Brixton Academy. The album also included two previously unreleased studio tracks, "The Grade" and "The Cowboy Song". That same year, the band contributed a track for the motion picture soundtrack to Bill & Ted's Bogus Journey with the song "The Perfect Crime". Jim Martin also made a brief cameo in the film as "Sir James Martin" as the head of the "Faith No More Spiritual and Theological Center". Mike Patton's original band Mr. Bungle would go on to sign with Slash/London's parent label Warner Bros. Records in 1991, following the worldwide success of The Real Thing.
