Who are his contemporaries in music?

Most pale in comparison to Mr Withers. There are some artist like Anthony Hamilton that comes to mind. I have so many wonderful memories growing up listening to his music. This was an excellent documentary on bill Withers and soul music that's not being heard by a younger generation. At the end of the film when he sings with his daughter it's as if he's passing the torch to another generation. I was happy and sad at the same time because this type of music isn't being made like it use to. But I guess what is.
