Hi,
I didn't see this addressed, so I hope it helps. My husband and I are very much into theatre and music. After reading one of the adoption books, he decided that we needed to have a music and entertainment collection that included black artists. The idea being that a young person needs to see and learn about people who look like him, who can be role models or just there to say, "Hey, if that guy can do it, so can I!"
He got recommendations from friends of all races and we added Ray Charles, Alicia Keys, Anthony Hamilton, and I can't think of all the rest. DH has always had jazz around, as he played the sax, and we're playing that for DS sometimes. ("Music makes you smarter!" - music executive trying to sell more stuff to neurotic parents?

) We also have a decent collection of R&B and old-school rap, much of which was here long before we decided to adopt.
We also have a large collection of comedy done by black comedians: Bill Cosby, Richard Pryor, etc. Again, this is DH's interest. We're trying to take advantage of our interests and learn more about black people in those areas.
I hope this all makes sense! It's late!
