Two aging outlaws swap reminisces and argue good-naturedly about who's caused the most trouble. Every once in a while they work themselves up to doing more damage. Small flashes of tossed-off brilliance appear in nearly every song, but sometimes it's hard to tell what's part of the pair's casual charm and what's just laziness: when the clever "Old Age and Treachery" (always overcome youth and skill) falls apart at the end, it's infuriating. Like much of either singer's output, Clean Shirt sounds a bit wrinkled at first, but most of the album holds up to repeated listening.
