Swing and jazz music was “unerwünschte musik” (undesirable music) for the nazis who worked hard to suppress this music during World War II, while using it at the same time for propaganda purposes on the airwaves. This is the story of the battle they lost against this irrepressible music. 95 tracks are included in this 4 CD set which comes with a 60 page booklet crammed with information about this fascinating period.
