Not sure who's aware of these guys, but I took the family to go see their show a few nights ago in Durham, NC.
If you dig percussion, up-tempo music and extreme visual effects, it's actually a really neat show.
There are a few skits and some audience participation pieces, but there is quite a bit of thought and technology that goes into these shows.
Honestly, I didn't think I was going to like it as much as I did. My family loved it - especially my 12 year old drummer.
They did a skit where they play percussion against three variable lengths of PVC and it really demonstrates how you can manipulate sound.
BTW, if any of you local guys haven't been there, the DPAC is a great venue.
