Following the dissolution of the Smashing Pumpkins in December 2000 and a brief stint moonlighting with New Order, Billy Corgan quietly put together his first official post-Pumpkins project in late 2001, a quartet known as Zwan. Not surprisingly, Corgan opted to enlist on drums his longtime musical foil and creative spark plug Jimmy Chamberlin, with the other half of the lineup rounded out with guitarist Matt Sweeney (formerly of Chavez and Skunk) and guitarist/bassist David Pajo (formerly of Tortoise and Slint). The group surreptitiously debuted in November 2001 with a series of four small club shows in the Los Angeles/San Diego area, followed by a brief jaunt through the Midwest the following month. Each of these two mini-tours boasted an entirely different set of songs, hinting at the wealth of material that the prolific band had already worked out in their few months together. In April 2002, bassist Paz Lenchantin (of A Perfect Circle fame) joined the group for a series of shows in St. Louis and Corgan's hometown of Chicago. These dates featured yet a third set of music, different from the previous two, bringing the total number of songs in Zwan's repertoire up into the neighborhood of 60. After inking a deal with Reprise, Zwan released their first single, "Honestly", in November 2002, with their debut album slated to follow in early 2003. ~ Steve Bekkala, All Music Guide
