The Secret Love Life Of The Octopus - Pierre Henry

[1967]

Abstract reverb drenched musique concrète.  

I would have liked to have heard the entire thing sans French fella voice over but that doesn't seem to be available on anything. 

Pierre Henry & Michel Colombier - Jéricho jerk [1968]
Musique concrète crossed with funky rock for novelty fusion fun in the 60s.

Pierre Henry - Appocalypse De Jean [1968]

Before industrial, dark ambient, drone and noise you had Pierre Henry and this epic one hour and forty minute apocalyptic musique-concrète jam.  

Biblical man!
