The True Poets of Zwan, commonly known simply as Zwan, was an American alternative rock supergroup that was formed by members of The Smashing Pumpkins, Slint, Tortoise, Chavez, and A Perfect Circle. Zwan was formed in late 2001 by Billy Corgan, lead singer and guitarist of the Smashing Pumpkins after they disbanded in December 2000. 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.
Despite being a short-lived band, Zwan is credited with being a bridge between the success of the Smashing Pumpkins in the 1990s and the further career developments and experimentations undertaken by Corgan in the 2000s, as well as his shift from his sombre, dark themes towards more hopeful lyrics in line with his spiritual development at the time.
Following the disbanding, Corgan released a solo album before reforming the Smashing Pumpkins in 2005, with Chamberlin joining him a year later. Chamberlin also released his own studio album and collaborated in various projects, as did Pajo who returned to release music under his alias Papa M as well as other monickers. Sweeney and Lechantin collaborated with various bands as both touring and session musicians, with the latter returning to A Perfect Circle to collaborate on Emotive. As of 2017, there is still tension amongst band members, and a reunion is not planned.
