Also, Chet Baker. If you want the really "blue" jazz, his work is a must hear.
Track name is "I'm a fool to want you" dunno what's up with the title, but an amazing live version, haunting performance. And when he stops singing to play a 'solo'..
Here, some older stuff from the god Django.
I hope I got what you need right.
Might post more if I find out the names again.
