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 have 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 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, and his grand musical ambitions and lyrics that often serve as a personal catharsis have shaped the band's albums and songs.The Smashing Pumpkins broke into the musical mainstream with their second album, 1993's Siamese Dream. The group built their following with extensive touring and their follow-up album, 1995's double album Mellon Collie and the Infinite Sadness, debuted at number one on the Billboard charts. With approximately 18.3 million albums sold in the United States alone as of 2006, 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 in their later years and led to a 2000 break-up. In April 2006, the band officially announced that they were reuniting and recording a new album. So far, the only confirmed band members are Billy Corgan and Jimmy Chamberlin.[ More ]
