Recording of selections from the Dixieland vs. Bebop concert held May 23, 1948, at the Music Hall at 9th and V Streets, NW, in Washington, DC. Advertisements for the concert indicate that Charlie Parker, Wild Bill Davison, Joe Sullivan, Sir Charles, and George Wettling were among the performers. These selections include tunes not included on the 2008 commercial release "Charlie Parker: Washington D.C. 1948," as well as enough overlap in content (C-Jam Blues, Tiny's Blues) to confirm the event.
