Dunno, maybe could do something really radical, like, maybe... splicing tape! Yeah, that's the ticket! (Pierre Henry? Who's he?)
The process here seems be more interesting than the results, but I'm not sure it's interesting enough to make up for the paucity of interest of the results. The idea of a musical montage evocative of a mysterious past was doable in a fairly precise way with very old technology; see Vergangenes. (You don't get much older than instruments that are blown, plucked, struck and scraped.) The idea of improvising such a montage to good effect with modern technology (a DAW, perhaps) is entirely doable; see much of Robert Fripp's output, such as When the Rains Fall.
This, however, has more in common with a Jean Tinguely sculpture, but maybe not as much fun for a crowd.
I am wary of work that relies on gimmicks. Schoenberg could and did write anything that suited him, tonal or atonal. Fripp can play damned near anything for guitar, with or without electronics. How far can these ladies take this before it palls? Can they make all of it work together to good effect? (No, I don't think they have so far - the sound is at least as important as the method, and they haven't nailed that.) Are there more effective ways of achieving what they're looking for?
Something to think about, perhaps.
