I particularly like the music in this little segment of Marie Chouinard's "Body Remix-Goldberg Variations". It's the inside of a piano whose hollow metal sound I have used myself for a couple of things. Chouinard brilliantly introduces the two girls on "strings" in the background of this piece which seems to redouble the effect of the piano. I found early on that I wasn't even watching the foreground dancers despite the very advanced and edgey dancing they are doing.
When an artist has her audience transfixed by the background, she's truly gifted.
