I think there is an element here when it comes to visual cues. Our total experience of a musical performance is guided, amongst a host of other factors, by both visual and auditive cues, and the interaction between these.
So basically, seeing someone perform an action that leads to a synchronous sonic result is different than just hearing the sonic result. This is kind of obvious with traditional instruments, but the same thing can be experienced by seeing an electronic music performer trigger a sample, or a DJ getting more into the music as the drop hits.
There is musicology research done on this topic, which I swear I read through, so I have at least some basis for this rambling 
But it has little to do with op, so to stay a bit on topic, I’ll throw in this:
As a concept, I would think about this in the Karenn mould. That is, have some prepared parts, improvise some parts, then loop something that works, use FX to extend and flesh out those loops, drop back into other prearranged parts. Rinse and repeat.
