Another favorite of mine is Blue Man Group. I first saw them years ago on the Tonight Show (I believe back when Johnny Carson was hosting). Becky and I saw them in Vegas and really enjoyed their show.
From the ever fun Podcast About Nothing I found a website that shows you how to make many of BMG’s PVC-based instruments. I don’t know if I’ll ever get around to doing it, but it’s good to have plans.
What I’d really like is a set of BMG samples to be used in Garage Band. That would be fun.
