I first encountered a few of these tracks on a Columbia Special Products album in the 99 cent bins (ask yr grandparents). This album is the one to start with if you are a jazz neophyte & want to hear Classic Jazz. Duke on piano, Harry Carney (on "Pyramid"), & Johnny Hodges (on any number) explode the Lawrence Welk rep of 'Big Band Music'. If you can listen to Cootie Williams work on "Echoes of Harlem" & not believe that a soul speaks, check your pulse! This is one of the essential recordings.
