A blues shouter is a blues singer, often male, capable of singing with a band. The singer must project, or "shout", to be heard over the drums and instruments of the band. Blues shouting is a major pathway by which jazz music edged over into rock and roll.
Notable blues shouters include:
Big Joe Turner, whose style changed hardly at all between 1938's "Roll 'Em Pete" and 1954's "Shake, Rattle and Roll".
Wynonie Harris
Eddie "Cleanhead" Vinson, an unusual combination of blues shouter and bebop alto sax player.
Walter Brown, of the Jay McShann orchestra
Jimmy Witherspoon, who also appeared with McShann
Jimmy Rushing, blues shouter with Count Basie.
