This is a fun video. I love playing music, and particularly percussion. I play a drum kit, but mostly just "bang on stuff". In fact, I used to get kicked out of class for drumming on the desk, and got kicked out of a drivers ed class for drumming on the steering wheel to the beat of the right-turn blinker. There's always something around to bang on, your chest or knees included, and everything makes a different sound. I believe rhythm is the foundation of all music. Even piano, which I love, is very much about timing and rhythm.
I like to pick up anything that makes a sound and have fun with it, structure the sounds you emit from it in a pleasing, syncopated way. (In fact, your own vocal chords are simply amazing, something this video didn't include.) It's of course even better with friends -- that's where the magic is. This video captures that fun -- even though the actual audio is obviously studio recorded, you get the idea. And I'd say it's even more fun when it's heard live and improvised. (Hmm, I need to go see a STOMP show, who's down?) Thought you'd enjoy.
