I remember a radio interview with some members of Pink Floyd concerning the making of _The Dark Side of the Moon_ and in particular some comments around the track _On the Run_. Anyone who knows this song will remember that it's very 'looped' and 'sampled' but, of course it was recorded before the advent of computers and (useful) synthesisers. In the interview they discussed using 'miles' of tape loops that were ranged across the studio floor during the recording to get the effects that they wanted. The quesiton is, are there any photos of this anywhere ? I'd love to see how it used to be done.
