Sorry, they're called Stomp
They've been around for years. I haven't seen them. All that banging and jumping on metal bins etc would just give me a headache after a very short period of time.
I've seen them on TV a few times, but I think they'd be so much better live.
Saw 'em on a Tiesto (Number 1 in the world) vid.
That was cool. Reminded me of the movie 'Drumline'.
Very cool sound.

IIRC they started out finding rhythm in everyday things. Brooms, matches, garbage cans,etc.
LOL or at least not be so annoying!
