What an awesome compilation of video game theme songs! At first I was like "wtf is this crap", then they started playing for real and I was like "AWESOME!"

Watch in high quality for extra fun.
A live performance for Seattle's Marrowstone in the City program. The music was arranged by the genius Lennart Jansson (Link) and myself (Ash Ketchum). I choreographed all the extra bits behind us as we play as well as sang the Halo theme, of course. The Tetris bit is a tribute to the old a capella group that did game themes. Lennart is playing an ocarina there, and I'm drumming the top of my violin. Hope you enjoy.

They look like kids, and if they created it then I give them major PROPS.
