Sometimes a good idea can box you into a corner. That's my theory about what's happening with "Unsung" (10 tonight), the terrific TV One series that starts a new season tonight.

As suggested by the title, the series aims to bring deserved light to artists who have not gotten their due. And it has done some stellar episodes featuring Phyllis Hyman, Debarge, Minnie Riperton, and Donny Hathaway.

Tonight, though, the premiere episode features Teddy Pendergrass. Teddy? Unsung? And later, there are episodes featuring George Clinton and the O'Jays, both Rock & Roll Hall of Fame inductees.
