Agree with Slipknot. One quick correction: "Nightfall of
Diamonds" was actually from the October 16, 1989 show at the
Meadowlands (yes I was there - Bob Weir's b-day). "Dozin' at the Knick" is a
compilation of the 3-night March, 1990 run at the Knickerbocker
Arena in Albany, NY (yeah I was there too). Both are awesome
soundwise and perfomance-wise but I like "Nightfall" better
simply because it is a single complete show.
Yeah 1988 - 1991 was truly a peak period for the band
(certainly the last). Another great live release on Arista
is "Without a Net" which is a compilation of live recordings from the
Fall 1989/Spring 1990 tours.
Also agree that the May 1977 tour may be one of their best
ever and there are at least two Dick's Picks releases from
that tour: Dick's Picks Vol. 3 (5/22/77) and Dick's Pick's
Vol. 29 (5/19/77 and 5/21/77).
The thing to keep in mind about the Dick's Picks releases
are that they are live-to-2-track soundboard recordings not
carefully produced multi-track recordings like the ones on
Arista. That being said the sound quality is generally
quite good for the Dick's Picks series.
