Query: A flawed, yet worthwhile, gem

I agree that this particular concert was not recorded properly, but the poor sound quality does not detract from the often breathtaking music. Miles Davis was always way ahead of his time and this concert was no different. Those who give it a good, patient listen will be rewarded. Miles on a bad night was still infinitely better than almost any other band on a good night.
