Layla stands as one of a handful of pillars of classic rock. The short-lived ensemble that was the Dominos provided an outlet for Eric Clapton to vent his then unrequited (and secret) passion for the wife of his best friend, George Harrison. Romantic anguish inspired Clapton to write and collect an embroiling and interconnected song cycle. Meanwhile, latecomer Duane Allman prodded Clapton to tear it up on guitar, so as not to be overwhelmed by his even more talented foil. Of course, Clapton eventually won the hand of his lady love. And then he divorced her. Sometimes real life messes up a good plot line.
