for soul/r&b, jodeci is the obvious choice although if they don't get into the whole death row and rape/kidnapping drama (which they most likely won't) than it's fukkin worthless. shyt a devante only episode alone would be some




shyt.
i'd say blackstreet or teddy riley just because of all the fukkery that teddy has been involved with over the years between Guy, Blackstreet and his solo work with artists.
as far as hip-hop goes, slick rick deserves one IMO. tribe is a given but their documentary already came out and although it left ALOTTA shyt out that fans wanted explanations about i doubt they would do one for them since their flick came out.
prince paul would be good cause of his history and his interesting personal, but he prolly is even too low profile for a show like "Unsung". i'd love to a pharcyde one too cause all the drama and stories i done heard about them brawling in the studio while jay dee was making beats would make for a very interesting documentary and fat lip is a crazy ass nikka.
