Sun Ra’s stride piano playing from 1946. This is early R&B with stop-time figures, driving bass, big-band-style comping, and tasty improv. Sometimes I lose sight of just how good Sun Ra was as a piano player. Later in his career some of his playing seems almost sloppy, even given that he often incorporated free playing into his compositions. This tune is tight, for sure.
Check out this article about Sun Ra. It’s a pretty good rundown.
