The Original Memphis Five was an early jazz quintet founded in 1917 by trumpeter Phil Napoleon and pianist Frank Signorelli. Jimmy Lytell was a member from 1922 to 1925. The group made many recordings between 1921 and 1931, sometimes under different names, including Ladd's Black Aces and The Cotton Pickers. Richard Cook and Brian Morton, writing for The Penguin Guide to Jazz, refer to the group as "one of the key small groups of the '20s".
