For Record Store Day this past weekend, Jack White attempted and completed a very Jack White-esque stunt: Recording, pressing, and releasing a new 7″ single in just over three hours, making it the world’s fastest single. For the occasion, he recorded a live version of “Lazaretto,” the title track from his forthcoming album. But since it wouldn’t be a proper 7″ single without a B-side, he also recorded one of those. And that single, a fearsomely bluesy cover of Elvis Presley’s late-’60s Memphis soul-rocker “Power Of My Love,” has made its way to the internet. Listen to it here.
