This time, video game music covers!

I thought I'd draw attention to CSGuitar89, who has done many covers of video game music on YouTube. See his site for his music, which isn't organized into albums, mostly mp3s. His Luigi's Mansion and Hyrule Field covers are pretty good, though a lot of his stuff is as well. His metal influences provide for very interesting covers.

Zelda Reorchestrated (Z.R.E.O.) makes some pretty good video game music, though specifically they use high-end synthesizers to update the music. Ocarina of Time is the only soundtrack they've updated entirely, but it stands much stronger with these revisions. Their Wind Waker stuff is also quite good.
