Elton John can be a master of the sleight of hand. The arrangements make it seem like there are substantial melodies underneath the tracks - but almost nothing demands repeated listenings. Similarly, he always sounds like he's singing up a storm, but his voice glosses over the material, reducing most things to an uninteresting sameness.

The Stones were always exemplary of one of the best of all rock qualities: tightness. They have always been economical, the opposite of ornamental. Having a very clear idea of what they wanted to say they could go into a studio and make it all up on a three minute cut.

James Taylor is the kind of person I always thought the word 'folksinger' referred to. He writes and sings songs that are reflections of his own life, and performs in them in his own style. All of his performances are marked by an eloquent simplicity.

Bob Dylan was the source of pop music's unpredictability in the Sixties. Never as big a record-seller as commonly imagined, his importance was first aesthetic and social, and then as an influence.

'Dance to the Music' was just Sly Stone being his natural crazy self right from the beginning. The man was an original and his first AM hit was nothing if it wasn't the example per excellence of the Sly Stone music machine.

While the Beatles always had George Martin around to clean up their act, the Rolling Stones had Andrew Loog Oldham to coarsen theirs.

The early Bob Dylan was compulsively drawn to the conflict between stability and the search for immortality.
