James Joseph "Jimmy" Chamberlin (born June 10, 1964) is an American drummer, songwriter, and producer. He is best known as the former drummer for the alternative rock band The Smashing Pumpkins. Following the 2000 breakup of the band, Chamberlin joined Pumpkins frontman Billy Corgan in the supergroup Zwan and also formed his own group, the Jimmy Chamberlin Complex. In 2005, Chamberlin joined Corgan in reforming The Smashing Pumpkins; he eventually left the group in March 2009 and performed in the group Skysaw until 2012. He is currently active / performs under the Jimmy Chamberlin Complex name and is working on a new album, which according to Chamberlin will be released "hopefully soon".
Chamberlin, who originally trained as a jazz drummer, cites jazz musicians Benny Goodman, Duke Ellington, Gene Krupa, and Buddy Rich, as well as rock drummers Keith Moon, Ian Paice, and John Bonham as major influences on his technique. While he is known as "one of the most powerful drummers in rock," he primarily strives for emotionally communicative playing. In 2008, Gigwise named Chamberlin the 5th best drummer of all time.
