Twenty 4 Seven is a Eurodance and Hip House act, created by Dutch producer Ruud Van Rijen in 1989. Other members of the group were rapper Tony Dawson-Harrison (left in 1991), later replaced by Stacey Paton (Stay-C), and female vocalist Nance Coolen, later replaced by Stella. As of 2007 Twenty 4 Seven made a comeback with vocalist Elle.
The combination of male rap and female choruses was the main recipe for their success. The first single, I Can't Stand It, a collaboration with Hanks & Jacks and MC Fixx it which even contained a bit of social criticism, reached #7 on UK charts in 1990. It was followed by another single, Are You Dreaming, which reached #17, and the debut album, Street Moves. more: WIKIPEDIA
