"But being a physicist, I said, ‘Suppose there were 1,000 people doing this; what would be happening?’ And I thought, ‘Well, you would be hearing them stamping. You would also be hearing a little bit of an effect, which is due to the distance that they are from you.’ So I put lots of individual repeats on them. Not an echo but a single repeat at various distances. And the distances were all prime numbers. Now, much later on, people designed a machine to do this. But that’s what we did. When we recorded each track, we put a delay of a certain length on it. And none of the delays were harmonically related."
