Correction to radio4forum's YouTube post titled "Acid House from 1958":
This 1959 track by Tom Dissevelt is not "Syncopation," it's titled "Vibration" (US title "The Visitor from Inner Space"). It's on a 2004 collection called "Popular Electronics: Early Dutch Electronic Music from Philips Research Laboratories, 1956-1963." Not much in common with 80s Acid house except that it is made with electronic sounds. Dissevelt was a jazzman; the loose, disjointed rhythm here might be called "swinging"--it's certainly more complex than Acid's usual 4-on-the-floor thump.
Not enough space in the comment box to say it's a great piece of music.
