With a musical palette that spans classical, jazz, tango, and the avant-garde, the Argentine composer/woodwind player Jorge Variego and his Jimmy Giuffre-inspired chamber unit with pianist Tabor Gable and bassist Rob Linton will perform in tandem with author Geoff Dyer’s readings from his classic, But Beautiful: A Book About Jazz, which Keith Jarrett proclaimed “the only book about jazz that I would recommend to my friends. It’s a little gem.”
