The Smashing Pumpkins is an American alternative rock band from Chicago, Illinois. The band was formed in 1988 by Billy Corgan and James Iha, with bassist D'arcy Wretzky and drummer Jimmy Chamberlin joining shortly after. Despite going through many lineup changes, the current lineup is identical to the original, with the exception of Wretzky, who would end up leaving the band just before their initial breakup in 2000. 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, shoegaze, grunge, and, in later recordings, electronica. Corgan is the group's primary songwriter; his 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, 1993's Siamese Dream. The group built its audience with extensive touring and their 1995 follow-up, the double album Mellon Collie and the Infinite Sadness, debuted at number one on the Billboard 200 album chart. 1998's Adore would just barely miss out, peaking at number two. With 30 million albums sold worldwide, the Smashing Pumpkins were one of the most commercially successful and critically acclaimed bands of the 1990s. However, internal fighting, drug use, and diminishing record sales led to a 2000 break-up. 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 the release of stand-alone singles, compilation 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 has released four albums so far—Shiny and Oh So Bright, Vol. 1 / LP: No Past. No Future. No Sun. in November 2018, Cyr in November 2020, ATUM in 2023, and Aghori Mhori Mei in August 2023. The last has been well received for its move away from the synth-heavy Cyr and ATUM, returning to the heavy guitars and drums of the band's 90s origins.
