Listening again to the O2 concert it has became clearer than ever that Led Zep’s sound is of Wagnerian proportions, dragging you through the Mississippi delta up to Norse and Celtic mythology and much in between and then back down to the delta.
Here are two decent enough interviews — the first is with Jimmy “biological research” Page (what a career, what a life!); the second with the three original members. They articulate, insofar as one can, what made them so musically special, as a group that is. The mysticality of the O2 performance is almost palpable devoid of some of the tiresome pomposity that marred The Song Remains the Same some thirty years earlier.
