I keep seeing this everywhere I go on the internets: Microtonals plus weird time signature changes equals Math Rock, I guess?
Let me know if you find that version on an album. I give up. Edit: Found it. I think. 1969 Velvet Underground Live with Lou Reed, Track 1. (I tried to find it almost as soon as you posted it. Found a half dozen radically different versions before I finally found it.)
