I know Serge Gainsbourg as a pop star, but apparently he started his career playing jazz. His jazz album is called Du Jazz Dans Le Ravin (Jazz in the Ravine) and is not bad.
Here’s a video I found on Youtube. It’s not from this album, but a recording from 1964, broadcasted on Belgium television. Serge Gainsbourg is on the piano in a trio with guitar and bass, playing All The Things You Are. Serge plays the theme and a chorus of improvisation, while Elek Bacsik plays four-to-the-bar accompaniment (which disturbes the piano chords a lot of times).
Serge Bacsik is actually a cousin of Django Reinhardt. He is from Romani descent, but worked and lived in the US (he played in Las Vegas a lot).
