One of the most talented singers of any era, k.d. lang has flirted with so many styles that everyone has a different impression or preference towards her career. Some hear a gifted purebred country singer, while others hear a nightclub torch singer. Any of her studio albums shows off her vocal talents, but this collection does a fine job of bringing together some of her finest moments in one place. “Constant Craving” (which the Rolling Stones nicked for the chorus of “Has Anybody Seen My Baby”), perfect duets with Roy Orbison on “Crying,” Tony Bennett on “Moonglow” and Jane Siberry with “Calling All Angels,” and virtuoso performances of the Beatles’ “Golden Slumbers / The End” and Leonard Cohen’s “Hallelujah” make a case for lang’s incredible versatility and show the respect that others hold for her in the recording industry. The Deluxe Edition includes live recordings from a radio broadcast at Malibu PAC that prove her talent is no fluke, as her stylized take on Neil Young’s “Helpless” is pretty, powerful and wild.
