Lyle Stevik 1976-2001
Phish, Spin Doctors and Widespread Panic, Blues Traveler -- none had as consistent a following as the Dead but they did have their devotees who would follow them around, sometimes following multiple groups around (e.g., both Phish and the Spin Doctors), and there was a lot of overlap between those groups and deadheads who didn't have an outlet after Jerry Garcia died. FWIW, he looks more like a Nirvana fan to me than the stereotype of someone who was really into Phish, but of course you can't tell a book by its cover.
Thanks. I'll start snooping around eBay for tickets and tour books. I'm looking at the Dave Matthews Band as well, they did a lot of touring in 2000/2001 and I've compiled dates for 3 different months of their 2000s shows.
