Other than the obvious, his small groups with Charlie Parker, Dizzy Gillespie does some of my favorite non-big band work on "Something Old, Something New," Verve, in a quintet with James Moody (who's super on this) and Kenny Barron.
As the title implies, they do a mix of bebop standards, including a wonderful medley of "I Can't Get Started" and "Round Midnight," and new (for 1963 when this was recorded) stuff. In the latter, I hear Dizzy, minus the mute, telling Miles Davis (and his second great quintet) that he ain't got nothin' over on old John Birks where sophisticated post-bop jazz is concerned. Barron cooks on "Cup Bearers." I might make "Early Mornin' Blues" my theme song for walking to work.
