"Machines", by Lothar and the Hand People. It comes from 1968. Not that you could tell by listening to it. It starts off like a latter-day Tom Waits song, with clanking percussion. It somehow morphs into the sort of herky-jerk you might associate with, say, the early scrabblings of the post-punk brigade. (I'm thinking of Snakefinger.) The singer at times comes across like Peter Garrett when he was a singer and not a politician. All of which is to say, you will have no idea what it sounds like until you hear it.
