D'arcy Elizabeth Wretzky (formerly Wretzky-Brown) was born on May 1, 1968 in Michigan, USA. Little is known about her childhood except that she had two sisters, one of whom is on the cover of the "Today" CD single. D'arcy has formal training on the oboe, but none on bass guitar, which she plays for the Smashing Pumpkins. As is stated in the biography for Billy Corgan, she met him outside a club in 1988, and joined the band a few days later. She then left for Germany, and called Billy when she returned, as he was still looking for a bassist. D'arcy had little training on bass. Billy liked her personality and attitude, which got her into the band. D'arcy also acts as background vocals for live performances, and has sung a few songs as lead vocals such as "Daydream", the cover of Blondie's "Dreamin'", and a verse with Jimmy Chamberlin on "Farewell & Goodnight".

D'arcy co-owns Scratchie Records with James Iha, among others. She enjoys listening to Air, Luscious Jackson, Beastie Boys, Nirvana, the Beatles, Red Red Meat, Chainsaw Kittens, and Catherine. She was married to Kerry Brown, drummer for Catherine, and also occasional drummer and producer for Smashing Pumpkins.

On September 9, 1999 after 10 years of service to the band, D'Arcy left the Smashing Pumpkins. D'Arcy did, however, play on the Pumpkins last record, "Machina: the Machines of God". Her position behind the bass guitar was taken by Melissa Auf der Maur for the upcoming tour. There was no public statement as to the reason for her departure, although she was arrested for drug possession shortly afterward.

When the band reformed in 2007, D'Arcy was not a part of it, and has had little media coverage since she left the band, aside from an impromptu Q101 phone interview in July 2009, during which she stated she wasn't healthy enough to be a musician, and an arrest for missing 4 court dates related to failure to control her horses.
