When copyright law meets the ‘mash-up’

clipped from www.boycott-riaa.com Record producer Brian Burton knew he’d done something technically illegal when he electronically blended tracks from the Beatles’ “White Album” and vocals from Jay-Z’s “The Black Album” into a CD called “The Grey Album.” But he was so excited by the mix of Fab Four riffs and Jay-Z raps that he badly wanted people to hear it. “When I was finished, it was the biggest sense of accomplishment I’ve had over anything,” he said. So in January, the Los Angeles-based Burton, who records as DJ Danger Mouse, made a couple of thousand copies of the disc and started mailing them out.
