I reviewed The Who's 1970 "Isle of Wight" DVD about a year or so ago. At that time I felt that it was the best example of a classic Who concert. While that may still be true to some degree, I must give a slight edge to this performance for one simple reason: the setlist.
Isle of Wight took place in 1970. But The Who's true genius, or shall I say the album that I feel launched them into classic rock legend status, came in 1971. Yes, "Tommy" was brilliant and we can't ignore the early hits by any measure, but "Who's Next" is what I consider to be their finest hour, with "Tommy" and "Quadrophenia" following close behind.
Here we get a partial performance of "Tommy" but we also get tracks from "Who's Next" and other then-recent works. This adds a better representation of what the classic lineup were capable of doing, and a better selection of the big hits (namely "Baba O'Riley" and "Won't Get Fooled Again") that remain fan favorites and classic rock anthems today.
And may I add, The Who are on fire here. They simply rock, pure and simple. The sheer energy that comes from the stage is phenomenal and power-packed. This performance is a gem to be treasured by every Who fan.
