American experimental music's foremost performer, pianist David Tudor remains as inextricably linked to many of the most groundbreaking pieces in the modern canon as their respective composers; long John Cage's most intimate associate, he also delivered virtuoso early performances of landmark works by Pierre Boulez, Earle Brown, Sylvano Bussotti, Morton Feldman, Karlheinz Stockhausen, and La Monte Young, many of them written expressly with Tudor in mind. He was born in Philadelphia on January 20, 1926, and throughout his teens played organ at the city's St. Mark's Church, later studying theory and composition under H. William Hawke and Stefan Wolpe. In New York on December 17, 1950, Tudor delivered the American premiere of Boulez's Deuxième Sonate pour Piano -- just the second performance of the piece anywhere, it immediately launched him to the vanguard of the experimental community.
