It was 2004, a dark time before Facebook or Twitter existed. While people carried on a dull existence one man brought a ray of hope and started a new movement. The man/marsupial was Danger Mouse and the movement was mash-up culture. His ingenious fusion of Jay-Z and The Beatles, known as The Grey Album, changed the game and resulted in furious litigation. Now the mash-up masterpiece is reborn, with a new remastered version from producer The John Stewart.
