This is a funny thread to me since I work in the live concert industry as a sound man.
You will be shocked to hear that I have seen over 100 Teena Marie shows since I have worked for her since 2003. Presently I have taken a new job with the band 'Cowboy Mouth' but since I just started, I have seen only about ten of their shows.
I have also worked for House of Blues (New Orleans and Chicago) since 1998 and I have seen SO MANY different shows as a result of working there. Often, as the 'house guy' I am asked to do monitor engineering for these bands. Here are just a few from the past few months:

The Hush Sound
Better Than Ezra
Mushroomhead
Al DiMeola
Twisted Sister (I was working that show, Yeag!)
Rev Luv (my friend's band-opened for Twisted Sister)
Redman
Method Man
Tower of Power
Peter Frampton
Three Dog Night
Sugarcult
Hatebreed
Victor Wooten
Yonder Mountain String Band
Old Crow Medicine Show
Pearl Jam (last year - hurricane Katrina benefit)
Robert Plant (opened for Pearl Jam last year)
the Subdudes
Shiny Toy Guns (damn, that girl is HOT!!)
and so many more...

Oh! and when I lived in New Orleans I worked for the Neville Brothers, the funky Meters, George Porter, Jr., Brides of Jesus, and Russell Batiste. Russell also got me a little bit of work with Vida Blue when he was doing that project with Page McConnell and Otiel Burbridge.

There is no way I could ever list EVERY band I heve ever worked with. Some artists are such idiots I have blocked those experiences out of my memory.

BTW: BOYCOTT HOUSE OF BLUES!! Please do the industry a favor and stop going to House of Blues shows. Since they were bought-out by Live Nation the company has been cutting corners at an alarming rate, stripping benefits from employees that have shown tremendous amounts of dedication. (myself included, and MANY others)
