Billy Corgan has revealed that there are more than 60 unreleased songs from his short-lived band Zwan, and that he plans to unveil them in a series of “different sets.”
Corgan formed Zwan in 2001 upon the breakup of The Smashing Pumpkins. The lineup featured Corgan’s Pumpkins bandmate Jimmy Chamberlin on drums, along with bassist Paz Lenchantin (A Perfect Circle), and guitarists David Pajo (Slint) and Matt Sweeney (Chavez).

Zwan only released one studio album, 2003’s Mary Star of the Sea, featuring the standout singles “Honestly” and “Lyric,” but broke up later that year. The Smashing Pumpkins reunited in 2006, and have been active ever since.

In a new video interview with Stereogum, Corgan was asked about Zwan, and he responded, “All the Zwan songs are gonna be remixed and remastered, that were on the original album Mary Star of the Sea, and there will be, like, maybe two more LPs of unreleased tracks.”
He continued, “Because there’s so much Zwan stuff, I’m gonna put it out in different sets. Otherwise the box set would be, like, 20 records long and it’s just too much to ask fans to take on. Sixty-plus unreleased Zwan songs that have never been released. Not just versions, like other songs. There was a lot of writing in that band.”
In the meantime, Corgan and the Pumpkins are celebrating the ongoing 30th anniversary of their landmark album Mellon Collie and the Infinite Sadness with a Fall 2026 North American tour. Tickets are available here.
