Boy, k.d. lang sure knows how to show adult alternative who's boss, doesn't she? On her 10th studio album, the indomitable ms. lang revisits each of the styles she's conquered: jazz (the easy, breezy "Sunday"), vaguely vintage pop ("Je Fais la Planche," which is so freaking crammed with whimsy you'll want to pinch its cheeks) and country (sort of; nothing's as twangy, or torchy, as her early material, but the front-porch folk-blues of "Jealous Dog" seems like an homage). As always, her interpretations are graceful and exquisitely subtle. This is what adult alternative should be.
