If you're a fan of the music of the original Castlevania for the Nintendo Entertainment System or the arrangements from Mega Man: The Wily Wars for the Sega Genesis, then you're familiar with the work of composer Kinuyo Yamashita.  While most of her gaming work hasn't left Japan, you can still enjoy this YouTube video of her performing a piano arrangement of her theme from Blizzard Buffalo's stage as heard in Capcom's Mega Man X3 for the Super NES.  It's a rare treat to see game music composers actually perform their work.  I wish more of them would make these kinds of videos available.
