The Real Thing is the third studio album by American rock band Faith No More, released on June 20, 1989 by Slash and Reprise Records. It was the first major release by the band not to feature vocalist Chuck Mosley. Instead, the album featured Mike Patton from the experimental/funk band Mr. Bungle. On this album, Faith No More continued to advance their sound range, combining thrash metal, funk, hip hop, progressive rock, synthpop, carousel music, and hard rock, along with what has been described as "a black sense of humor".
As I recall the story, all the music was written when Chuck Mosley left the band. They brought in Mike Patton and he wrote all the lyrics in a week.
