Dizzy Gillespie Sextet “All the things You Are/Dizzy Atmosphere (78 Musicraft). Recorded Feb 29, 1945.
Per the book THE BIRTH OF BEBOP by Scott DeVeaux (1997) (P.364): "in the history of bebop, 1945 was the decisive year. At its outset, Dizzy Gillespie and Charlie Parker were still edgy young professionals, fighting to make names for themselves in a crowded field... And, of course, they made recordings. Their efforts in the studio from the first months of 1945... include the earliest surviving veresions of much of its core repertory - "Dizzy Atmosphere"... as well as the first collaborations between Gillespie and Charlie Parker in the small-combo format."
