Sounds great! Very well played, properly mixed and recorded. The one criticism I would offer is that the whole things sounds anticipatory - you're always waiting for something to happen, but nothing ever does. Kinda like an overture or an introduction, but without any resolution. You keep thinking "this is where the lead starts", or "this is where the lyrics start", but they don't. I could see it as the basis for a kick-ass tune, but it needs a direction.
But, that's just me, and what do I know? I couldn't come up with anything that good or play that well if my life depended on it.
