There were a couple of comments about the sound quality of the last post, but since the imbalance appears to be inherent in the CD (not the rip), I thought the best solution would be to post this...
Essentially it's the same trio session from 1961 as for Angel Eyes, featuring Thomas Howard and Lex Humphries, but without the track Angel Eyes (not sure about why they felt the need to do that). In Japan this was on the Jazz Line imprint, whereas in the US it seems it was on Black Lion. Same difference for me.
