Not bad!
I'm loving the jazzy grooves in this submission. The prime thing holding the piece back, though, is lack of build-up. It's just too content with hiding in the background, you know? Some bass (and a little backing synth here and there) would have really added to the character of the music. I can see what you were going for at 0:42, but without bass and some synth to enhance the crescendo, it just sort of recedes, and suddenly breaks into a slightly too sketchy solo, which also could have used the aforementioned instruments. The last thing that could have used some work is the ending. The fade-out is just another reason to forget this song. An intro like this song's needs to be followed by increasingly powerful additions, and a solid, heart-pounding outro would have really done that. Instead, though, we get this little faded intro. It was a little disappointing.
Anyhow, this really wasn't a bad piece at all. The riffs were fantastic, the guitar and drums in the solo were epic, and the entire song has a TON of potential. The only real criticism I have is on the production aspect. If properly produced, this song would have me addicted in seconds.
