Machina/The Machines of God is the fifth album by 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 first breakup in 2000. A sequel album-Machina II/The Friends & Enemies of Modern Music-was later released independently via the Internet.
As with its predecessor Adore, Machina represented a drastic image and sound change for the band that failed to reconnect the band with chart-topping success. However, after the relatively brief Adore tour, the new lineup featuring Chamberlin and former Hole bassist Melissa Auf der Maur mounted longer international tours that returned the live incarnation of the band to guitar-driven hard rock territory.
