The Smashing Pumpkins have announced their highly anticipated twelfth studio album; a three-act rock opera album titled ATUM (pronounced Autumn). ATUM will feature 33-tracks, and is the sequel to 1995's Mellon Collie and the Infinite Sadness and 2000's Machina/Machine of God. ATUM was written and produced by Billy Corgan over the past 4 years. ATUM is a rock opera presented in three acts by inimitable American rock band The Smashing Pumpkins. The album tells an epic interplanetary story set in the not-too-distant future, though the songs themselves respectively stand on their own in the Pumpkins pantheon. This is the final installment in a concept album trilogy, which began with 1995's Melancholy and the Infinite Sadness and then continued with 2000's Machina/The Machines of God. The album features three original members of the band-William Corgan, James Iha, and Jimmy Chamberlin-as well as longtime guitarist Jeff Schroeder.
