When you've racked up more than 20 albums in your long career, curveballs, while not entirely out of the question, aren't expected or even welcomed. The cozily familiar music on John Hiatt's 21st album won't win him any new fans at this point, but those who've been there for the long haul will appreciate the bluesy shuffle of "We're Alright Now" and "It All Comes Back Someday"'s pop push. Mystic Pinball is reliable roots rock from an old master.
