The Hot Mix 5 are an American DJ team originating from Chicago, Illinois, who were chosen by WBMX Program Director, Lee Michaels in 1981. The founding members were Farley “Funkin” Keith (later known as Farley “Jackmaster” Funk), Mickey “Mixin” Oliver, Ralphi Rosario, Kenny “Jammin” Jason, and Scott “Smokin” Silz. In 1982, Scott Silz was asked to leave the group and was replaced by Julian “Jumpin” Perez in 1984, as the winner of a HMF sponsored DJ Battle. Another DJ, Jeff Davis, was supposed to be a sixth member, but Silz mentioned in an interview that he never showed up, leaving just the five members. Julian’s tenure as a member was about a year and then, Mario “Smokin” Diaz, became a member of this Legendary group and played with them throughout their radio time in Chicago.
