In addition to folk, Leventhal was an ardent supporter of world music. He produced the debut New York performances by the likes of Jacques Brel, Miriam Makeba, Nana Mouskouri and Ravi Shankar, and also embraced jazz by showcasing the Modern Jazz Quartet and others. But his most enduring contribution to American music remains Bob Dylan's April 12, 1963 appearance at New York's Town Hall, the singer/songwriter's first metropolitan concert performance. The list of acts under Leventhal's representation also included such giants as Joan Baez, Johnny Cash, Harry Belafonte, Phil Ochs, Judy Collins, and Peter, Paul Mary. He was the executor of Woody Guthrie's estate and also hired the icon's son, Arlo, as an office boy. In 1969, Leventhal produced Arlo's film musical #Alice's Restaurant, and for over three decades oversaw the singer's annual Carnegie Hall holiday concert. Leventhal also produced the 1976 Woody Guthrie biopic #Bound for Glory as well as #Wasn't That a Time, which documents the Weavers' much-acclaimed 1980 reunion. He won a Grammy for his production work on the 1989 LP Folkways: A Vision Shared--A Tribute to Woody Guthrie and Leadbelly, and that same year earned an Emmy for the television film #We Shall Overcome. In 2002 Leventhal received the Folk Alliance Lifetime Achievement Award and was the subject of his own all-star Carnegie Hall tribute in 2003, the basis of the documentary feature #Isn't This a Time!. He also was widely acknowledged as the inspiration for Irving Steinbloom, the fictional folk impresario whose death and subsequent memorial concert sparks Christopher Guest's acute folk satire #A Mighty Wind. Leventhal died October 4, 2005 at the age of 86. ~ Jason Ankeny, Rovi
