you find very few, if any, strictly "black/urban gospel" videos out there. my adice would be, since those genres are such a mixing pot of styles, just try to be well versed in the different styles that make it up, and then combine what you learn. whether it's rock, jazz, r&b, blues, country (yes, it applies).......get all those elements at your disposal and you'll be surprised at how quickly the stuff you want to learn will come to you.
