I have it, and it's fantastic. Interestingly enough, it's taken from the March 6 & 7, 1970 Fillmore show (I'm not sure which one). The opening act was the Miles Davis Quintet (with Wayne Shorter and Chick Corea). The March 7th Miles show was recorded and documented as "It's About That Time: Live at The Fillmore East." Put on the Miles and follow it up with the Neil! It's almost like being there!
it's a great album, but I think it's very disappointing it's not the whole show, only 35 or so minutes...
