Mosby, who also sometimes played violin, created a connection with his roots by originally calling his Los Angeles band the Kansas City Blue Blowers. Under any name his groups helped him establish a solid reputation in Los Angeles, although Mosby was not the type to wait around for someone else to heat up the coffee. His knack for self-promotion resulted in Mosby opening his own clubs, beginning with the famous Apex and also later including the Oasis in 1949.
As a composer, his activities included scoring sections of King Vidor's 1929 "black" musical entitled #Hallelujah. His group itself has several features in the movie, including accompanying Nina Mae McKinney on Swanee Shuffle and running through a band theme, Blue Blowers Blues, as the background to a comedy routine. In the '30s, Mosby's group was part of a touring variety show that promised to Change Your Luck. Archive labels such as Jazz Oracle have reissued Mosby's early material. ~ Eugene Chadbourne, Rovi
