William "Billy" Patrick 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 in 2005 and a collection of poetry (Blinking with Fists) before setting his sights on reforming Smashing Pumpkins.
The new version of The Smashing Pumpkins, consisting of Corgan and a revolving lineup, has released and toured new albums extensively since the 2007 reunion album, Zeitgeist. He began a large project to release songs over the course of a long period, Teargarden by Kaleidyscope, and released two EPs and two standalone singles as part of it from 2010 to 2011. Reverting back to albums, The Smashing Pumpkins released Oceania in 2012 and Monuments to an Elegy in 2014. In October 2017, he released his first solo album in over a decade, Ogilala.
In 2011, Corgan entered the world of professional wrestling, founding Chicago-based Resistance Pro Wrestling. He later joined Total Nonstop Action Wrestling (now known as Impact Wrestling) in 2015, becoming its president in August 2016. After leaving TNA in November 2016, Corgan purchased the National Wrestling Alliance (NWA), gaining its ownership in October 2017.
