I wanted to make a quick plug for the Root City Band. These guys ROCK. Mr. Aaaron Heaton, aka Heatbox, went to Park Center with some of my close friends. His beatboxing is crazy. I'll see if I can't get some of his recent work and post it.
In a recent review I found this: The bands blues heartbeat is nicely rounded out by thier timely injections of rock and soul. ~Louis Lenzmeier
Check 'em out. The perform quite a bit around Minneapolis, and even up in Duluth.
