This is a song about Marcel Duchamp, arguably one of the most influential artists of the latter 20th Century. Specifically this -- the sixth song on And -- is a song sorta about his heart rate at rest.
The album version differs from the Junto draft, the drumbeat is less obviously different since vocals now dominate the track. Voice wasn't an obvious choice but, like Wind-up, I was thinking about Andrew Weatherall's advice to producers.
