Mutemath make some great music videos.

Typical. In this one they had to learn to play the song backwards, so that when they reversed the video it looked like they were playing it normal. Apparently it took them six months to master.

Blood Pressure. And in contrast to six months, this one took them a day but it is some brilliant stop-motion. I just love their ability to be creative on a budget. Spoiler: The drummer can fly.
