The Smashing Pumpkins are an American alternative rock band that formed in Chicago, Illinois in 1988. While the group has gone through several lineup changes, The Smashing Pumpkins consisted of Billy Corgan (vocals/guitar), James Iha (guitar/backing vocals), D'arcy Wretzky (bass guitar/backing vocals), and Jimmy Chamberlin (drums/percussion) for most of the band's recording career.

Disavowing the punk rock roots shared by many of their alt-rock contemporaries, the Pumpkins have a diverse, densely layered, and guitar-heavy sound, containing elements of gothic rock, heavy metal, dream pop, psychedelic rock, arena rock, shoegazer-style production and, in later recordings, electronica. Frontman Billy Corgan is the group's primary songwriter—his grand musical ambitions and cathartic lyrics have shaped the band's albums and songs, which have been described as "anguished, bruised reports from Billy Corgan's nightmare-land".

The Smashing Pumpkins broke into the musical mainstream with their second album, Siamese Dream (1993). The group built their audience with extensive touring and their follow-up, the double album Mellon Collie and the Infinite Sadness (1995), debuted at number one on the Billboard charts. With approximately 18.25 million albums sold in the United States alone, The Smashing Pumpkins were one of the most commercially successful and critically acclaimed bands of the 1990s. However, internal fighting, drug use, and diminishing sales hampered the band and led to a 2000 break-up. In April 2006, the band officially announced that it was reuniting and recording a new album. Returning members Billy Corgan and Jimmy Chamberlin were joined by musicians Jeff Schroeder (guitar/vocals), Ginger Reyes (bass/vocals), and Lisa Harriton (keyboard/vocals) in 2007 to tour in support of their new release, Zeitgeist.
