The Smashing Pumpkins is an American alternative rock band from Chicago. Formed in 1988 by frontman Billy Corgan (lead vocals, guitar), D'arcy Wretzky (bass), James Iha (guitar), and Jimmy Chamberlin (drums), the band has undergone many line-up changes. The current lineup features Corgan, Chamberlin, Iha and guitarist Jeff Schroeder. Disavowing the punk rock roots of many of their alt-rock contemporaries, they have a diverse, densely layered, and guitar-heavy sound, containing elements of gothic rock, heavy metal, dream pop, psychedelic rock, progressive rock, shoegazing, and, in later recordings, electronica.
