Does he mean 'Plain' or 'Plane'?
Anyway, Paul Kelday had been farting around with his electronic devices, literally making 'Farting' noises, since around 1974. So this gives him the right to be the 'Daddy' of the DIY UK Electronic Underground. The Grandaddy being 'Trevor Wishart' of course.
This is as far away from 'The Berlin School' sound one could possibly wish for, and has more in common with the abstract electronics of Asmus Tietchens, and The BBC Radiophonic Workshop than Edgar Froese.
Lots of funny electronic noises,tape loops,found sounds and echo effects, rather than repetitive hypnotic melody lines, were the order of the day for Paul.Either because he was incapable of playing a synth's keyboard,if he had one, or it was a conscious decision. Either way this would make a good soundtrack for a 'Forbidden Planet' remake.
