I got home late from a night of great music at a place called Studio Blue. It gave me a looping riff in my head, actually; so I stayed up til 4 having a blast with it in Reason.

At this point, it's all about figuring the next place to take it. I could layer in stuff on top of the same riff, or chop it up, or half-time, etc. etc....it's like stumbling in the dark until I find the rocket launcher.
