Ah, no. He didn't. The aural clues that humans use to guess
position of sounding things (apart from not being very precise) 
are not such that you can record them separately from "the sound"
and present in any speaker setup. (Similarly you can't take 
a photo that would have the same colours in any light).
With eg voices, we can sometimes make good guesses on their
position independently of speaker placement (if they were 
recorded in a more or less well-known room), but this 
wouldn't work for an explosion or the sound of mating ants 
or a good Buchla patch or other less familiar sounds.

The British experimental pop group / Aleister Crowley church
Psychic TV did an album largely using the Zicarelli "Ringo"
head. It's quite a good death-and-rebirth concept album with
mostly unprocessed concrete sounds (of course) - growling dogs, 
karate instructor, uzi fire etc; you get the drift - and 
some pop and industrial-type music.
The head recordings sound quite good even in loudspeakers,
and are downright creepy in headphones (after being chased
with dogs, poor Ringo is burnt at the stake, then put inside 
a coffin and buried).

The album is called "Dreams Less Sweet". Came out in 1983 
or so. If you see it second hand somewhere I think it's 
well worth picking up.


Oh, ps. At the time I got the impression the Z. head is 
a binaural thingy built to have the same sonic properties 
as a human head. It would thus emulate the cranial conductivity, 
hair phase splitting etc. So it would be at least as good as 
any other figure head (though I doubt you can get much further
along that path).


Cheers,
