That's not to say that the record is a one-dimensional pummeling session. Inferno features two guest guitar solos from Steve Vai (see if you can spot them; Phil Campbell's an underrated axeman in his own right) and closes with the acoustic "Whorehouse Blues," a track that indicates a possible future path for Lemmy. He's going to turn 60 next Christmas, after all, and his lyrics have often showcased self-mocking humor and a bluesman's swagger. Why shouldn't he go that route, a few more years down the road, if his liver holds out?
