 The rich tradition of four-part harmony reached its peak in the late 1930s and 40s. What had been a gospel and vaudeville vocal style was adapted to popular songs, and the Mills Brothers, along with the Delta Rhythm Boys were the premier groups that captured America s attention. Their vocal stylings laid the groundwork for generations of Pop and Soul groups to follow! Here are rare, early appearances by all three of these landmark groups - all on one sensational DVD. No fan of pop or rhythm and blues should miss out on this extraordinary collection!
