help me find quality classic jazz?

I am looking for early jazz recordings (1930 to 1950 I imagine). I like the standards done right or any obscure, quiet, simple jazz featuring guitar, piano, saxaphone (not fast saxaphone but slow, breathy and intimate) drums etc.

I think you get the idea, I like the old stuff but not interested in Swing or Big Band type of music but more like Billy Holiday or Charlie Christian

Any and all recommendations appreciated

for convienience I prefer CD but vinyl is fine too just often costly to find new.

thanks everyone

Phil
