 Starting with the Eckstine band's session for the De Luxe label on December 5, 1944 ("If That's the Way You Feel, I Want to Talk About You, Blowing the Blues Away, Opus X, I'll Wait and Pray, The Real Thing Happened to Me"), bebop recording sessions grew more frequent.Parker had left the band by that date, but it still included Gillespie along with Dexter Gordon and Gene Ammons on tenor, Leo Parker on baritone, Tommy Potter on bass, Art Blakey on drums, and Sarah Vaughan on vocals.
