That one dude knows his stuff.
Deadheads Try To Guess Year Of Grateful Dead Live Recording Based On 10 Sec Clips

These are several videos of deadheads attempting to guess the year of a live Grateful Dead recording after listening to just a 10 second clip. The guy in the first video — he knows his stuff. Me? If I followed the Dead around for even one year I guarantee by the end of it I wouldn’t even be able to tell you who I was following.

Keep going for the video, including a father and son duo in the third video.
