The Smashing Pumpkins are an American alternative rock band that formed in Chicago in 1988. While the group has gone through several lineup changes, The Smashing Pumpkins consisted of Billy Corgan (vocals/guitar), James Iha (guitar/vocals), D'arcy Wretzky (bass/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, progressive 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."
