Instrumentals need to invariably build up to a solo, or a dynamic climax, and I was slightly disappointed that there was nothing like that in the changes. I just kept waiting for a melody to guide the music but nope. Also while your guitar tone was totally bitchin' the synthesized drums are very obvious when you blast the double bass pedal without changing the note velocities to simulate performance. But I mean if this had lyrics and a real drummer it would be a tight ass song man.
