Miles Davis, still in his very early days, recorded some unreleased tracks with vocalists Earl Coleman and Anne Baker in 1946. These bluesy bop numbers were released under the album name "Bopping the Blues". The performances are very mellow and shows Miles at a young age, and that early bebop sound. It's not well developed but it is an interesting take on the blues.
Of interest, are Gene Ammons on sax Art Blakey on the drums.
The album only has 4 songs but each one has 4 alternate takes.
Here's 'Don't Sing me the Blues' with Earl Coleman on vocals.
