A couple of my favorites were left out:

"Big" Al Anderson - the complete package; an absolutely amazing 
player, a great vocalist and songwriter.

Marshall Crenshaw - somewhere around 1991's "Life's Too Short" he 
turned himself into a heck of a player (he was no slouch to begin 
with).  His latest album is full of tasty (if mellow) playing, and he 
gets a great sound.

Nils Lofgren - his solos on "Youngstown" and "Worlds Apart" on the 
last couple of Springsteen tours were vivid reminders of how good he 
is.  He's also written a few good songs along the way...
