 As someone who doesn't know anything about the dead, how would you sell the class to me? Well, I would say there were a lot of 60s cymbals that didn't even make it into the 70s. The Grateful Dead made it into the 90s. You know, it's an extraordinary story. These middle-aged rockers were peaking in 1991, 20 years after Woodstock. That makes the connection between these fans and the band a little clearer. They aged together.
