Mavis Staples "Live Hope at the Hideout" (2008)

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.
