Myself, I started seeing them in 1983, toured heavily on the East Coast starting in '85, and more or less dropped off for awhile by '88, seeing a few shows a year after that. My memories of the mid-'80s shows are largely colored by my fondness for the experience of being there, not necessarily for the actual playing on the tapes.
Don't get me wrong, though; there were plenty of well played hot as a pistol shows in '84 and '85, but there were also many where Jerry's obvious drug problems and Phil's heavy drinking at the time took a heavy toll. Lots of shows from that era are particulary sloppy, truth be told. Plus, it was about "83 where Jerry's voice really started to wear out, I always thought.
Out of the loop? I didn't know there was a loop!
