The blues covers album isn't that bad, just dull. I was thinking it would be a good late-career "coasting" move to release a strong of those à la Dylan's or Rod Stewart's "standards" discs (back before Dylan went serious again) but now it looks like they'll never put out another album or, if they plan to, they're tempting Father Time. Underwhelming all around is really a good way to put it. Not sure if underwhelming (Blue and Lonesome) or generic-geriatric-Stones (Bang) is a worse way to go out. The last Jazz Butcher album was really good.
Haven't been listening to new albums lately, just burning playlists to CDs and listening to those. Sometimes that's just all you want to do, and that's OK.
