Dafydd Rees and Luke Crampton enjoyed London-based careers in the music business before co-founding the Media Research & Information Bureau (MRIB) in 1981, which became the largest chart-compiling and music research agency in Europe. They have written over 20 music and media-related books, and have produced numerous successful UK and US radio and television series, including the Network Chart Show and more recently, CNN International's World Beat and The Music Room, the world's only global weekly music shows.
