ZwanRock band. Formed 2001. Disbanded 2004
Zwan Biography (Wikipedia)
Zwan was an American alternative rock supergroup that was formed by Billy Corgan and Jimmy Chamberlin, lead singer and guitarist, and the drummer of The Smashing Pumpkins respectively, after they disbanded in December 2000. Other members included bassist Paz Lenchantin, of A Perfect Circle, and guitarists David Pajo and Matt Sweeney of various prior bands and projects. The band released only one album, Mary Star of the Sea, in 2003, before breaking up acrimoniously that same year during their world tour to promote the album. Following the disbanding, Corgan released a solo album, TheFutureEmbrace before reforming the Smashing Pumpkins in 2005, with Chamberlin in 2006. Despite allusions to multiple album's worth of material written by band members, no further material has surfaced beyond their only studio album, and none of the material has ever been revisited in performances by any of the members outside of a brief 2017 tour by Corgan. In his solo shows in the summer of 2019, Corgan played "Honestly" and "Endless Summer" on his European summer tour at some dates.
