There is a wonderful recent collection by the contemporary Fisk Jubilee
singers available.

Also, if you have some interest in these 19-th century genres, you might
like to get the 4-cd collection "Wade in the Waters," which has some nice
spirituals and so forth.

A great book that I would recommend is by my colleague and friend at
Michigan State, David Stowe:  HOW SWEET THE SOUND.  It also comes with a cd,
that provides much of the music discussed in the book.
