On April 26, 2011, Corgan announced that the Smashing Pumpkins would be releasing a new album titled "Oceania", which he labeled as "an album within an album" in regards to the "Teargarden by Kaleidyscope" project, in the fall. As with the previous recording sessions, all four band members contributed to the project. Also, the entire album catalog was to be remastered and reissued with bonus tracks, starting with "Gish" and "Siamese Dream" in November 2011. The pre-"Gish" demos, "Pisces Iscariot", and "Mellon Collie and the Infinite Sadness" were released in 2012, with "The Aeroplane Flies High" released the following year. "Adore" was released in 2014, and "Machina/The Machines of God" and the yet commercially unreleased "Machina II/Friends and Enemies of Modern Music" are expected to be combined, remixed, and released in the same year. The band did a thirteen-city US tour in October 2011 followed by a European tour in November and December.
