A jazz vocalist with a bluesy tone, Mary Ann McCall worked with Charlie Barnet in the late 1930s, leaving the band in 1940. In the mid-1940s she sang for Woody Herman's First Herd, most notably on the recordings ''Wrap Your Troubles in Dreams'' and ''Detour Ahead.'' During 1947 and 1948 McCall worked with the Ralph Burns Orchestra. She also sang for Tommy Reynolds and Teddy Powell. In the 1950s she recorded several albums under her own name, working with such artists as Charlie Ventura, Teddy Charles, the Phil Moore Orchestra, and the Ernie Wilkins Orchestra. In 1987 she came out of retirement to perform at a Woody Herman tribute concert just a few days before the bandleader's death.
