I’ve seen the Groovie Ghoulies at least ten times. Probably more. I’ve seen the Mr. T Experince about seven times. I’ve seen the Queer and the Hi-Fives about fivetimes each. Seen Cake five times…
I won’t even talk about the local bands that open for every damn show. How many times can one see the Lesdystics before one gets sick?
Hey Jackknifed Juggernaut, cool name you’ve got yourself there.
Unfortunately, I’ve only seen Radiohead once, because they conveniently skipped Detroit a few times. I did finally see them in Chicago on what I guess would be the Amnesiac tour. Now that I’m in DC, I am sure I’ll see them countless more times.
Seen Travis twice. GREAT live band.
Saw Sloan twice.
That’s it… I’m really not the concert-goer I should be. 
The Allmans, Fleetwood Mac when it wa still Peter Greens band, Hot Tuna, Flo & Eddie
Marillion- 3 times
Depeche Mode 3 times- twice in the 80s, once in the 90s
U2 twice- once in the 80s, once in the 90s
Crowded House twice- once when they first started out, then right before they broke up. Wish I’d seen the tour where the Finn Brothers performed Split Enz music!
I’ve seen Moxy Früvous at least two dozen times, maybe more.
After that you could divide it pretty evenly betwixt DMB, Blues Traveler and a handful of others at 4-5 times each.
The Marvelous 3–twice
Train–twice (one when no one knew who they were, another time when they had JUST started getting recognized)
My Friend Steve–twice
Probably the most interesting band I’ve seen was The Urge. I only saw them once, though I had a chance to see them again.
I was going to see Better Than Ezra for the second time on August 31 but the concert was rained out.
Excluding local bands, or bands where I was dating someone involved (see Ever Date A Celebrity thread, can’t be arsed to find the link to it), my answers would be Blur and Lush. I don’t know exactly how many times I’ve seen them, but I’d guess about a dozen each.
