But that leads me to another stray thought. I once worked in the loading dock of RCA when it had a plant in Sydney. Right next to the loading dock was a plant room that processed vinyl for processing. It used to have this hypnotic hum, probably an A, that went on all day. I used to find myself humming along to it and creating vague Indian harmonies and melody lines to this tambour-like background. It whiled away the time.
