Tyree Glenn, who had the unusual double of trombone and vibes, was an important asset at various times to both Duke Ellington and Louis Armstrong. Glenn started out working in territory bands in Virginia, then moved to the West Coast, playing with groups headed by Charlie Echols (1936) and Eddie Barefield. After playing with Ethel Waters and Benny Carter, he became a longtime member of the Cab Calloway Orchestra (1939-1946). Glenn visited Europe with Don Redman's big band (1946). During his association with Ellington (1947-1951), he was an effective wah-wah trombonist in the Tricky Sam Nanton tradition and Ellington's only vibraphonist, being well-featured on the "Liberian Suite." During the 1950s, Glenn worked in the studios, led his quartet at the Embers, and freelanced in swing and Dixieland settings. Other than some European dates in 1947, Glenn's only extensive opportunity to record was for Roulette (1957-1958 and 1961-1962). During 1965-1968, he toured the world with Louis Armstrong's All-Stars. After leaving Armstrong, Tyree Glenn led his own group during his last few years. ~ Scott Yanow
