Nicky Hopkins worked with just about every legendary band from the British Invasion. Credit the pianist’s stylistic range: He could play hard and loose; simply listen to The Beatles’ “Revolution,” The Who’s “Anyway, Anyhow, Anywhere,” or any one of the many Rolling Stones sides on which he’s featured. Yet he was just as skilled at laying down perfectly simple chord progressions in service of gorgeous tunes like The Kinks’ “Sunny Afternoon.”
