William Patrick Corgan Jr. (born March 17, 1967) is an American musician, songwriter, producer, poet, and professional wrestling magnate. 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.
Following a brief stint touring with New Order in the summer , Corgan reunited with Chamberlin to form the band Zwan with Corgan's old friend Matt Sweeney in late 2001. According to Neil Strauss of New York Times, during his few live performances with the band, Corgan says "is still a work in progress." The lineup was completed with guitarist David Pajo and bassist Paz Lenchantin. The band had two distinct incarnations, the primary approach being an upbeat rock band with a three-guitar-driven sound, the second, a folk and gospel inspired acoustic side with live strings. The quintet performed throughout 2002, and their debut album, Mary Star of the Sea, was released in early 2003 to generally positive reviews. In the midst of their supporting tour for the album, mounting conflict between Corgan and Chamberlin, and the other band members led to the cancellation of the rest of the tour as the band entered an apparent hiatus, formally announcing a breakup in September 2003.  In 2004 Corgan began writing revealing autobiographical posts on his website and his MySpace page, blaming Iha for the breakup of the Smashing Pumpkins, calling Wretzky "a mean spirited drug addict," and criticizing his former Zwan bandmates' fixation with "indie cred" and calling them "filthy", opportunistic, and selfish.  On September 17, 2003, Billy first presented his poetry at the Art Institute of Chicago's Rubloff Auditorium. In late 2004, Corgan published Blinking with Fists, a book of poetry. Despite mixed reviews, the book debuted on the New York Times Best Seller list. Around this time, he began posting autobiographical writings online under the title The Confessions of Billy Corgan.  Also in 2004, he began a solo music career, landing on an electronic/shoegaze/alternative rock sound for his first solo album, TheFutureEmbrace, co-produced and arranged by Bon Harris of Nitzer Ebb. Released on June 21, 2005, through Reprise Records, it garnered mixed reviews from the press and only sold 69,000 copies. Corgan toured behind his solo album with a touring band that included Linda Strawberry, Brian Liesegang and Matt Walker in 2005. This tour was not as extensive as previous Smashing Pumpkins or Zwan tours. Prior to recording TheFutureEmbrace, Corgan had recorded some 72 songs inspired by Chicago history for the largely acoustic ChicagoSongs project, which have yet to be released. CANNOTANSWER
2001-2005: Zwan and solo career
William Patrick Corgan Jr. was born at Columbus Hospital in Chicago's Lincoln Park neighborhood on March 17, 1967 as the oldest son of William Corgan Sr., a blues/rock guitarist, and Martha Louise Maes Corgan Lutz. He was raised Catholic. His parents had one more son, Ricky, before divorcing in 1970. His father was soon remarried to a flight attendant, and Corgan and his brother went to live with them in Glendale Heights, Illinois. During this time, Corgan alleges he was subject to much physical and emotional abuse by his stepmother. Corgan also developed a protective bond with his younger paternal half-brother, who had special needs as a child. When Corgan's father and stepmother separated, all three boys would live alone with the stepmother, with both of Corgan's birth parents living separately within an hour's drive.  Corgan, who grew much faster than his fellow students, was a strong athlete in elementary school. In addition to being a member of his Marquardt Middle School baseball team, he collected baseball cards (amassing over 10,000) and listened to every Chicago Cubs game. However, by the time he began attending Glenbard North High School in Carol Stream, Illinois, he had become only an average athlete. He decided to start playing guitar when he went over to a friend's house and saw his friend's Flying V. Corgan gave his savings to his father, who bought him a used Les Paul knock-off. Corgan, Sr. steered his son stylistically, encouraging him to listen to Jeff Beck and Jimi Hendrix, but offered little other support, and the younger Corgan taught himself to play the instrument. His musical interests in his formative years included hard rock like Guts-era John Cale, heavy metal pioneers Black Sabbath, and mainstream rock like Queen, Boston, ELO, Rush, and Cheap Trick. In high school, Corgan discovered alternative rock through Bauhaus and The Cure.  Corgan performed in a string of bands in high school, and graduated as an honor student. Despite grant and scholarship offers from a number of schools, and a tuition fund left by his grandmother, Corgan decided to pursue music full-time. Not finding the Chicago music scene to his liking, he moved from Chicago to St. Petersburg, Florida in 1985 with his first major band, The Marked (so named for the conspicuous birthmarks of both Corgan and drummer Ron Roesing). Not finding success in St. Petersburg, the band dissolved; Corgan moved back to Chicago to live with his father.  Corgan performed with Wayne Static in Static's first band Deep Blue Dream, in 1987/88. CANNOTANSWER
