One of the songs on my playlist is Kid Beyond's Mothership, (totally fun and awesome and energetic) which I need sometimes (especially when working on this stupid never-ending bathroom remodel-grrrr!) But what I didn't realize until just now when I was trying to find the lyrics on youtube is that Kid Beyond is-himself- the entire band...instruments included. He does live looping beatbox, which is where he records a sound that he makes with his mouth, and then he loops that as he records more and more sounds and layers them on until he has the most incredible music.
Even if you aren't a Kid Beyond fan, even if you've never heard of live looping before, watch the video. He's amazing.
