Michael Burks
Coco Montoya
Buddy Guy
anyone who uses Double Trouble as their backing band - those two are so tight it's unbelievable, you don't realize this until you see them live.
The Blasters original lineup of Phil, Dave, John and Bill + Lee and then later Gene. The intermediate incarnations without Dave and now without Dave, Bill and Gene, are not worth the cost of the ticket.
Ray Charles
Oingo Boingo (esp. their Halloween shows)
Beat Farmers (you had to be there though, doesn't come through on video)
Roger Waters
Jimmy Thackery
Roy Rodgers
Sonny Landeth
John Hiatt & The Goners (The Goners have been long since disbanded)
King Crimson (it's all about Fripp)
Bella Fleck and the Flecktones
Chris Issak & Silvertone
Tom Jones
Agree on Peter Wolf and J.Geils Band. As for BOC, when I saw them, they were awful, just awful.
I'm sure I'll think of a few more later.
