For a few years now, I have been working with Rick Kramer on his Joia tubes. It is a percussion instrument that I compare to something you would see played by the Blue Man Group. I make the (one and only) wood stick that stretches between the legs and Rick does the rest. Well, Rick has outdone himself. Always pushing the creative envelope, he now has a set that lights up when you hit the tubes. And, I thought they were fun to play before. I have a feeling that Rick is going to need more sticks.
Check out the short video. I think it is Rick (he is also in a percussion group called Joia) playing the Joia tubes.
