The original performance was really good, but the individual drums weren't "popping" in the way I wanted. So I went through and took the original individual pieces, and blended sampled drums into the kick/snare/tom parts in order to better isolate and pan them.
What that (hopefully) resulted in is a live stereo drum performance that has better clarity and "push" to the track than the original - which I thought sounded kind of muddy and indistinct on its own. Adding sample blends over individual parts IS the original performance, just slight enhanced for sonic distinctiveness.
