Billy Corgan Announces Release of Over 60 Unreleased Zwan Tracks

Zwan was created in the wake of the Smashing Pumpkins’ 2001 breakup. The supergroup’s lineup comprised frontman Billy Corgan, drummer Jimmy Chamberlin, guitarist Matt Sweeney, and bassists David Pajo and Paz Lenchantin. In 2003 the band issued its sole studio album, *Mary Star of the Sea*, which featured the lead single “Honestly.” The group dissolved a few months after the album’s release.

Corgan has disclosed that the Zwan archives contain more than 60 previously unheard songs, not merely alternate mixes but distinct compositions. He plans to issue the material as two additional LPs—or in multiple smaller sets—rather than a single expansive box set that could exceed twenty records. All tracks are slated to be remixed and remastered before public release.

In a video interview with Stereogum, Corgan confirmed that the unreleased songs will be formally released and emphasized the need to present them in manageable collections. He noted that the volume of material would make a twenty-record box set impractical for fans. No specific release schedule or distribution format has been announced.

• “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.” — Billy Corgan, Stereogum interview

• “[There are] 60-plus unreleased Zwan songs that have never been released. Not just versions, like other songs. There was a lot of writing in that band.” — Billy Corgan, Stereogum interview

The forthcoming releases would more than double Zwan’s publicly available output, providing listeners with a broader view of the band’s creative work beyond *Mary Star of the Sea*. Remixed and remastered versions will improve audio fidelity, reflecting Corgan’s plan to present the material in a quality suitable for listeners.

Current sources agree on the existence of “60-plus” unreleased tracks but do not disclose an exact figure. Details regarding the release timeline, physical versus digital formats, and pricing remain absent from public statements.

Corgan has indicated that the material will be released in separate sets after remixing and remastering, but he has not provided a target date. No further details about the rollout schedule or distribution channels have been released.
