This is a fascinating album if you are into Mile's 70's music. I agree that the sound quality is not the very best, but it is still pretty good and acceptable. This is funky electronic music that should not be judged with once or twice listening. One of the great advantages of this double cd compared to the rest of the Miles live double cd reissues by Columbia is the absence of Electric "Corea and Hancock"! This double cd does not have the distorted and overly powered electric keybord sound that the other double cd reissues have. Again if you are into early 70's Miles music buy this cd and enjoy the trip. My only complain as with other double live cd's is that both cd's are in the 80 minutes range, and should have been put in one single cd.
