Here's just a sample...

Rush
Kansas
The Grateful Dead and all its spinoffs
Widespread Panic
String Cheese Incident
Old Styx
Yes and most of its spinoffs
ELP and most of its spinoffs
Jethro Tull
Pink Floyd
Various combinations of Crosby, Stills, Nash and Young
Cold Play
Talking Heads
Queen
Modest Mouse (what little I've heard)

Most of the above I've seen in concert. I saw the Dead 3 months before Jerry died.
