Barthes

"The 'grain' of the voice is not—or not only—its timbre; the signifying it affords cannot be better defined than by the friction between music and something else, which is the language (and not the message at all)." (273)

Oscar Peterson & Clark Terry - Mumbles (live version)

Can - Pinch (0:00 - 9:28)
(Note: I could only find the whole album, not the specific song. Just listen to Pinch. You also need to turn the speed up 2x in the video to get it to play normally.)
