On his birthday on March 26, 2016, original guitarist James Iha joined Billy Corgan, Jimmy Chamberlin, and Jeff Schroeder on stage unannounced at the Ace Hotel in downtown Los Angeles. He performed a few songs, including "Mayonaise", "Soma" and "Whir" marking his first appearance with the Smashing Pumpkins in 16 years. Iha also played at the second of the two Smashing Pumpkins shows at the Ace Hotel the following day, which was Easter Sunday. Iha joined the Pumpkins for a third time at their concert of April 14 at the Civic Opera House in Chicago. In July, Corgan began hinting of the possibility of reuniting the band original lineup, of himself, Iha, Wretzky, and Chamberlin, and in August, he stated he had begun reaching out to the original lineup about the feasibility of a reunion, including speaking to Wretzky for the first time in sixteen years. Despite the comments, Corgan would spend much of 2017 working on solo material – recording and releasing the solo album "Ogilala" and beginning work on another solo album for 2018. In June 2017 Chamberlin also mentioned the possibility of a reunion tour in 2018. In January 2018 Corgan shared a photo of himself, Iha, and Chamberlin together in recording studio. In February 2018 Corgan announced that he was working with music producer Rick Rubin on a future Smashing Pumpkins album, that there were currently 26 songs he was actively working on, and that "the guitar feels once again like the preferred weapon of choice." Soon afterwards, Corgan shared a photo of sound equipment with Iha's name on a label, as well as announcing recording was finished on the album.
