The Smashing Pumpkins (also referred to as simply Smashing Pumpkins) are an American alternative rock band from Chicago. Formed in 1988 by frontman and guitarist Billy Corgan, bassist D'arcy Wretzky, guitarist James Iha and drummer Jimmy Chamberlin, the band has undergone several line-up changes since their reunion in 2006, with Corgan being the sole constant member since its inception. The current lineup features Corgan, Chamberlin, Iha and guitarist Jeff Schroeder. Disavowing the punk rock roots of many of their contemporaries, they have a diverse, densely-layered sound, containing elements of gothic rock, heavy metal, dream pop, psychedelic rock, progressive rock, shoegaze, and electronica in later recordings. Corgan is the group's primary composer; his musical versatility and cathartic lyrics have shaped the band's distinctive albums, which one writer described as "anguished, bruised reports from Billy Corgan's nightmare-land". With 30 million albums sold worldwide, the Smashing Pumpkins were one of the most commercially successful and critically acclaimed bands of the 1990s, often cited as an important act in the popularization of alternative rock music. However, internal conflicts, drug use, and diminishing sales led to a break-up in 2000. In 2006, Corgan and Chamberlin reconvened to record a new Smashing Pumpkins album, Zeitgeist. After touring throughout 2007 and 2008 with a lineup including new guitarist Jeff Schroeder, Chamberlin left the band in early 2009. Later that year, Corgan began a new recording series with a rotating lineup of musicians entitled Teargarden by Kaleidyscope, which encompassed stand-alone singles, EP releases, and two full albums that also fell under the project's scope—Oceania in 2012 and Monuments to an Elegy in 2014. Chamberlin and Iha officially rejoined the band in February 2018. The reunited lineup released the album Shiny and Oh So Bright, Vol. 1 / LP: No Past. No Future. No Sun. (2018), Cyr (2020) and is scheduled to release Atum: A Rock Opera in Three Acts in three increments across 2022 and 2023. History Early years: 1988–1991 After the breakup of his gothic rock band The Marked, singer and guitarist Billy Corgan left St. Petersburg, Florida, to return to his native city of Chicago, where he took a job in a record store and formed the idea of a new band to be called the Smashing Pumpkins. While working there, he met guitarist James Iha. Adorning themselves with paisley and other psychedelic trappings, the two began writing songs together (with the aid of a drum
