We've seen it plenty of times: A guy sits in a room with a bunch of instruments, performing music from a cartoon or video game. Sometimes the performance is only decent. Sometimes, it's excellent. This is one of those second times.
Here's Collarblind Music with a one-man performance of Yasunori Mitsuda's Millenial Fair theme from Chrono Trigger. It starts out nicely enough, but eventually goes in some very cool, odd-meter directions. Good show! He says he's doing the Wind Scene music next. I'm looking forward to it.
