Keep goin
The instrument that came in around 1:17 was very nicely done. And, the instrument that came in around 2:00 in the background very lightly was good.
I know it was an experiment with loops, so I won't suggest that you make it less loopy..since it seems that was the point :)
Well, I really liked it all in all, and it wasn't excruciatingly long either! Good length!
