Hal Blaine, one of the most prolific and influential drummers of his generation, has died at the age of 90.
Over the course of his career, he played on countless hits by Frank Sinatra, Elvis Presley, the Beach Boys and John Lennon, amongst others.
But his most recognisable riff was the "boom-ba-boom-crack" bar that opened The Ronnettes' Be My Baby.
