I downloaded these this week. These were shot by Justin Kreutzmann. I've scanned through them and the video isn't really the best but the audio is fine. However, if you really like collecting Dead stuff and like all that behind-the-scenes stuff (even though we probably don't understand half of what's going on), you'll like these.
