I'm in, though I'm a Keith Godcheaux fan, so for me, the goods are about 1972 to 1978, with the sweetspot being '74 to '77.
I have all the Dave's Picks releases (there are about 30 now) and they are to a unit, stellar. All full concerts, all impeccably recorded.
I am NOT a studio fan, though, except for Terrapin Station and Anthem Of The Sun (if you like Crimson, you'll like AOTS; it was recorded almost exactly like Starless and Bible Black).
The more "typical" dead (American Beauty, or the Brent Mydland years) I can take or leave, and I CAN'T STAND Pigpen's singing ("Turn On Your Love Light" is a wasted 20 minutes for me).
