Smashing Pumpkins ‘ frontman Billy Corgan has revealed that he plans to formally release over 60 songs from his short-lived supergroup Zwan. In a video interview with Stereogum , he noted the songs will be remixed and remastered and feature tracks from their only album to date, plus two records’ worth of unreleased material.

“There will be, like, maybe two more LPs of unreleased tracks,” he said. No further details regarding the release date have emerged. “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,” Corgan added. “[There are] 60+ unreleased Zwan songs that have never been released. Not just versions, like other songs. There was a lot of writing in that band.”

Zwan was founded in the wake of Smashing Pumpkins’ breakup in 2001. The band was comprised of Corgan, drummer Jimmy Chamberlin, guitarist Matt Sweeney, and bassists David Pajo and Paz Lenchantin. Zwan’s only album, Mary Star of the Sea , was released in 2003, and featured the lead single “Honestly,” before they broke up later that year. Corgan reassembled with Smashing Pumpkins in 2006 and brought Chamberlin onboard until his departure in 2009.

The group’s 13th album Aghori Mhori Mei was released in 2024, with Kiki Wong was announced as the band’s new guitarist that same year following a nationwide scout.
