One problem with recording by artists once they hit "legend" status is that that recordings are just too polite. An easy way around that is to do a live album. The energy should prevent things from getting too staid, and the touring band isn't quite as awed as a bunch of studio musicians.
This live album does a good job of showcasing Staples at this latter point in her career. While she doesn't quite have the range that she did as a younger woman, she can still do a fantastic job.
