Music Factory

Music Factory (as known as The Music Factory Entertainment Group) is a UK promotional remix service that started in 1985. To this day, the service provides monthly Mastermix albums with exclusive mixes to qualified disc jockeys, as well as having provided a number of spinoff services over the years (some remixed, some not). It is also responsible for the Jive Bunny and the Mastermixers releases that were made commercially available.
