2009 two CD set. These bands, these swingers, could really swing. Before Rock `N" Roll became a byword for rebellion, before it was understood and accepted just how much American music was actually Black American music, these musicians - black and white - got down to business and, as the world went to war, their popularity soared. 40 tracks including cuts from Artie Shaw, Glenn Miller, Frank Sinatra, Benny Goodman, Duke Ellington and many others. Simply.
