Just found out about http://www.dreamingtree.org.
This site has almost every stinking live DMB available. Shows are taped with an external mic by various "tapers". Essentially DMB got their start by playing at popular locations during spring break ect, and college kids were trading tapes of the shows back at their home campus. Since this is what spread DMB a lot in the beginning, Dave has always allowed anyone who wants to use audio recording equipment at the shows even to this date. People used to be able to plug into the soundboard for recordings but apparently these were being sold without approval so that stopped. Some of the shows have decent quality for an externally taped live recording.
