I just got the 6-LP box set yesterday. I don't have any other TP albums, though I did go to one of those Fillmore shows, so I figure this one should cover the bases. Listened to the first LP last night - performance and sound quality are superb!!!
I was amused, though, when looking at the booklet inside - it starts with an essay from Mike Campbell about these shows. In his first sentence, he talks about how great it was to play the Fillmore West. They did not play the Fillmore West, which was about a mile or so East of the Fillmore Auditorium, where they did play. At that point, the Fillmore West had been closed for decades. There's often confusion about that, but proof-reading is good!
