Do you mean that the sound is better than the official, original album ("At Fillmore") or better than the original bootlegs?
In any case, if the sound is decent, it looks very good.
This re-issue is much better than the original
At Fillmore, IMO. Also, having the complete sets is a plus. Packaging, though, is not so great. I would have preferred a more substantial box, and the booklet is not as good as previous accompanying texts for these "complete" boxsets. Still, on balance, this is a very good purchase for fans of this period in Miles' career.
