Real Name: Byron Walton Jamie Principle, house music producer and vocalist born in Chicago, Illinois. He began having entries on the Hot Dance Music/Club Play chart in the early nineties, including "Cold World," a #22 dance hit that is a collaboration with Steve "Silk" Hurley. His 1985 track "Your Love" (with Frankie Knuckles) is arguably the earliest house track, although as early house is indistinct from disco there were other songs from the era that contributed to the new genre in mid 1980's Chicago.
