King Oliver

King Oliver was the widely regarded pioneer of the use of mutes in jazz, a technique he developed to emulate the vocal cries and moans of blues singers. His Creole Jazz Band in Chicago, which featured a young Louis Armstrong, produced landmark recordings like 'Dipper Mouth Blues.' Oliver's compositions were heavily reliant on traditional blues progressions, His role as Armstrong's mentor and leader of the Creole Jazz Band makes him a central figure in the transition from New Orleans ensemble jazz to the modern soloist era.
