Iggy Pop (born James Newell Osterberg Jr., April 13, 1947) is an American singer, songwriter, musician, and actor. Known for his wild, unpredictable stage presence, shirtless performances, and raw, aggressive music, he is widely regarded as one of the most influential figures in rock history — the ultimate proto-punk icon who helped pave the way for punk, alternative, and modern rock. THE STOOGES ERA (1967–1974, reunions later) Iggy formed The Stooges in Ann Arbor, Michigan.
