If we're now counting shows we've seen since the first one, these are the ones off the top of my head: I've seen Social Distortion more times than I can count (I'm a little in love with Mike Ness), The Street Dogs, Gov't Mule, The Allman Brothers, Buckwheat Zydeco, the Radiators, Marcia Ball, The Dropkick Murphy's, Aerosmith a couple of times, Motley Crue, Poison, Def Leppard, Cinderella, Cheap Trick, Weird Al, Jason Mraz, Gavin De Graw, and the musical comedian Stephen Lynch. Oddly I'm not really an 80's fan but both my best friend and my ex-husband are which explains a lot of those shows... I've also seen Bruce Springsteen and Bon Jovi quite a few times each because I was born and raised in Jersey and I just end up at one or the other every summer.
I also traveled down to Memphis for a couple years in a row to the Beale Street Music Festival and the highlights of those shows (besides Social Distortion) was seeing The Black Crowes, Aretha Franklin, Buddy Guy (who walked into the crowd and played a guitar solo standing face to face with me), The Plain White T's, and Jack's Mannequin.
