Wow, with all respect, I could not disagree more. I think a recording is a completely separate thing from a live gig. The process is not important to me; the finished product is what matters. And I don't care whether what I'm listening to meets the criteria for being "jazz." I want to hear good music. In fact, I consider Teo Macero to be a member of the band (Miles's band, not Erroll Garner's). I, sort of, agree with you except I don't know who decides what's "good music". You're being a little grumpy IMHO. BTW, I'm a fan of Concert By The Sea.
