Brilliant!
The organ section that comes in during the second round of the main groove? That's what I was talking about when it comes to having a melody. The only thing I could see to improve on this piece further is to introduce that section earlier on (like, say, the first time through) and then variate it each time it comes back.
Otherwise, this was five minutes of awesome, Shawn. Keep up the good work! :D
