Machina/The Machines of God is the fifth studio album by the American alternative rock band the Smashing Pumpkins, released on February 29, 2000, by Virgin Records. A concept album, it marked the return of drummer Jimmy Chamberlin and was intended to be the band's final official LP release prior to their initial breakup in 2000. A sequel album, Machina II/The Friends & Enemies of Modern Music, was later released independently via the Internet, and in highly limited quantities for the physical version.
