In fact, Danger Mouse had made waves before the Grey Album, working with Jemini on Ghetto Pop Mix. Included on the mixtape was Danger Mouse’s remix of Nas’s ‘It Ain’t Hard To Tell’ which he’d spliced with Beth Gibbons singing ‘Roads’. (Now that’s what I call a segue.) ‘Roads’ had originally featured on Portishead’s classic debut Dummy. It is/was a contemporary alt-hip-pop masterpiece.
