The music on this disc rates five stars. The sound on Disc Four is breathtaking, and the demos are pure gold, especially for those interested in the evolution of a songwriter (Neil Young's "Down Down Down" demo, for example, contains elements of two future masterpieces, "Broken Arrow" and "Country Girl"). My complaint is the usual one voiced by those who review this monumental set--WHERE THE BLOODY HELL ARE THE LIVE TRACKS??? They have to be out there somewhere--it's hard to believe that there are no live recordings in existence of a band whose live performances are legendary for their passion and ferocity. Maybe, as I've heard (hopefully) expressed elswehere, they are being held back for another compilation. I understand the bootlegs STAMPEDE and SELL OUT offer amazing live performances with poor sound. Can't all the recording industry's modern technology clean up those tapes enough to satisfy the artists and let all of us here just how amazing this band was on stage? C'mon, guys, give us a break.
