If you don't start singing along when you hear Blackstreet's "No Diggity" or "Don't Leave Me," we assume your ears have been stolen. This show finds the R&B kings—featuring Teddy Riley, pioneer of the dance-friendly late-’80s/early-’90s soul sound known as New Jack Swing—cobilling with another Riley outfit, Guy, as well as veteran crooner extraordinaire El DeBarge.
