This is an HDCD-encoded 4-CD set of music recorded live at the Fillmore East in April, 1971. Even if you are not a tie-dyed in the wool Deadhead, you may find a lot to like in this recording, especially if you have a soft spot in your heart for the psychedelic '60s.From the opening "Truckin'" right on through the final notes of "We Bid You Goodnight," many of the classic Dead tunes are presented in all their live glory. Yes, there are times when things sound a little sloppy, but for the most part, the band is really cooking and the "hits" (which of course none of these tunes were, at least for the Dead themselves) just keep on coming.If nothing else, this 4-CD set is amazing in that it document the fact that already in 1971, the Dead could already perform so many tunes that have came to be identified with them over the next 25 years or so. My goodness, what a prolific band!
