Which raises the question: Why did it take Plant and Krauss 14 years of being besieged with pleas for a follow-up to come through with one? “The question you ask is one that everybody asks,” Plant says, batting away its inevitability. With drummer Jay Bellerose and guitarist Marc Ribot returning as band members, and new additions such as jazz great Bill Frisell and Los Lobos’ David Hidalgo, the album sounds warm, mystical and at times slightly foreboding, like an old friend you’re glad to see again who’s still a little mysterious.

The other wildly eclectic songs range from “Can’t Let Go,” originally popularized by Lucinda Williams, to an 18-year-old song by the indie-rock group Calexico from an under-remembered Merle Haggard classic to a nearly century-old tune by a blues singer who only ever cut six tracks and left no surviving photographs.
