The Thad Jones/Mel Lewis Jazz Orchestra was a jazz big band formed by trumpeter Thad Jones and drummer Mel Lewis in New York in 1965. The band performed for twelve years in its original incarnation, including a 1972 tour of the Soviet Union during the height of the Cold War. The collaboration ended in 1978 with Jones suddenly moving to Copenhagen, Denmark, after which the band became the Mel Lewis Jazz Orchestra. Since the death of Lewis in 1990 it has been known as the Vanguard Jazz Orchestra. They have maintained a Monday-night residency at the Village Vanguard jazz club in New York for five decades. The band won Grammy Awards for the album Live in Munich in 1978 and for the album Monday Night Live at the Village Vanguard in 2009.
