Alan Parsons became an assistant engineer at Abbey Road while The Beatles were recording their last albums there. He got a chance to work on those timeless classics, and moved on to be the producer of Pink Floyd’s Dark Side Of The Moon, one of the all-time best rock albums. But then he crossed to the other side of the artistic pond, singing and playing the keys in his own band. His 1982 album Eye In The Sky is the epitome of great progressive pop.
