Charles Douglas Musselwhite is an American blues harmonica player and bandleader, one who came to prominence, along with Mike Bloomfield, Paul Butterfield, and Elvin Bishop, as a pivotal figure in helping to revive the Chicago Blues movement of the 1960s. He has often been identified as a "white bluesman".
Musselwhite was reportedly the inspiration for Elwood Blues, the character played by Dan Aykroyd in the 1980 film, The Blues Brothers.
