I hate to be the token hater, but here goes!
This guy is way better sounding than most game cover bands, but still seems kinda amateurish to me. The clean guitar parts, which pop up far too often, sound like shit -- especially at the end of the Brinstar track, which would've been just great without it. There's no bass at all in any of the songs from what I can tell, which really would've added to the tunes. It's just guitar over guitar over guitar over guitar. The drums are canned (midi), which is understandable though a bit of a cop-out. Also, the spoken/sung parts are totally out of place and sound idiotic, especially on the last track. The arrangements aren't bad, though it sounds like he's been listening to way too much Dream Theatre; the constantly switching odd time signatures sound totally forced to me.
Of course, it's still great overall. I just think all the claims that this guy is "god-like" (on his message board) are really pushing it. He sure aint bad for a kid with a 4-track, though. I should probably stop trying to rain on his parade and just be happy that someone is rocking ass at least decently well, since it's so much better than "The Advantage" and almost all of the other game cover projects out there.
