Just the other day, this nifty little Mega Man 2 medley popped up. It's a rock arrangement with keyboard accompaniment of the Metal Man and Heat Man themes.
On guitar is Ferdk, a videogame cover artist with a couple of free song collections available on Bandcamp. Check him out if you'd like to hear more. He had me hooked on his Sonic 3 Ice Cap Zone rendition.
No offense to the guy, but the real draw of this video is the pianist: Laura Shigihara of Plants vs. Zombies fame! She is adorable as always, especially with her arm cannon pew pew pew during the introduction.
