Grohl’s lawful-good lifestyle presents an eternal conflict between being unable to hate the guy and being unable to enjoy the music he continues to make. Foo Fighters seem to approach their formative rock, hardcore, and punk influences with the prompt, “What would be fun to play on Guitar Hero?” If the Guitar Hero reference feels dated, wait until you hear their new music. Their 10th album, Medicine at Midnight, adds very little to their extensive catalog of interchangeable power pop and hard-rock sing-alongs. But you can’t hang them on their own music, because Foo Fighters would never dare to give you enough rope to do it.
