I'm with pattyclink --- blues? gospel? I think Mahalia Jackson said that in blues there is no hope as opposed to gospel where there is hope.

For bluesy sound --- Mahalia Jackson singing "There is a Balm in Gilead"

For gospel --- medleys --- New Born Again/Standin' in the Need of Prayer --- We Shall Walk Through the Valley/Precious Lord (Take My Hand)

(New Born Again and We Shall Walk Through the Valley are in the 1975 Baptist Hymnal)
