After the movie 2001 Space Odyssey, I recall there was a remix in the radio, some sort of remix that had some sound of apes, and also some electronic feeling. It contained the Also Spratch Zaratustra and after that the electronic part came.
The only problem is that I never knew the name.
Is it familiar to you? Any lead?
There have been many versions of this piece. I remember, for example, Eumir Deodato's version, although probably it is not what you have in mind.
