Ten City (derived from intensity) was an American, Chicago, Illinois-based R&B and house music act, that enjoyed a number of club hits and Urban radio hits in the late 1980s and early 1990s and was one of the first exponents of deep house. Formerly known as Ragtyme, the group comprised vocalist Byron Stingily, guitarist Herb Lawson and keyboardist Byron Burke and were augmented by producer Marshall Jefferson. The group was signed by Atlantic Records and released the album Foundation in 1989, which became the group's only album to cross over, peaking at No. 49 on the US Top R&B/Hip-Hop Albums chart.
