Related documents: [0]  [DOC] William Patrick "Billy" Corgan Jr. (born March 17, 1967) is an American musician, songwriter, producer, poet, and entrepreneur. He is best known as the lead singer, primary songwriter, guitarist, and sole permanent member of The Smashing Pumpkins. Formed by Corgan and guitarist James Iha in Chicago, Illinois, in 1988, the band quickly gained steam with the addition of bassist D'arcy Wretzky and drummer Jimmy Chamberlin. Strong album sales and large-scale tours propelled the band's increasing fame in the 1990s until their break-up in 2000. Corgan started a new band called Zwan, and after their quick demise, he released a solo album ("TheFutureEmbrace") and a collection of poetry ("Blinking with Fists") before setting his sights on reforming Smashing Pumpkins.

[1]  [DOC] Monuments to an Elegy is the ninth studio album by American alternative rock band The Smashing Pumpkins, released on December 5, 2014. Band leader Billy Corgan has noted that—similar to the band's previous release, "Oceania"—the album is a part of the ongoing project, "Teargarden by Kaleidyscope". The album received generally positive reviews from music critics, but sold poorly compared to the band's previous albums, peaking at number 33 in the U.S. and number 59 in the U.K., thus making it their lowest charting album in both regions since their debut, "Gish" (1991).
