As promised, we bring you part four of last weekend's mp3 experiment brought to you by SOMA and Full Ammo Improv. Today we find our participants pretending to be monsters, running around like crazy and laying down all over the Pollock quad.

If you're just finding out about the mp3 experiment, make sure to check out parts one, two and three. And stay tuned for part five, the finale tomorrow. You'll want to tune in.

Here's a hint, more white folks dancing to music in their heads.
