Diana Krall is purportedly the most commercially successful jazz artist recording today. We, admittedly, are not jazz aficionados, yet we do own the last 4 of Krall's cds. So it seems we might be in a good position to speculate as to the reasons for her popularity. We would suggest that those reasons have to do with her being white, blond, attractive, highly publicized and immensely talented. Up to this juncture, her strengths have been her rich, smokey vocal interpretations of, mostly, jazz/pop standards and her brilliant piano styling. Now Krall has suddenly become a triple threat. All it took, apparently was for her to exchange vows and rings with Elvis Costello and she is now a compelling and accomplished songwriter, as well. Half the songs here are Krall-Costello collaborations-mostly haunting, brooding, melodically complex, lyrically suggestive songs which require the most focus and patience. Nevertheless, they reveal another intriguing facet of Ms. Krall and clearly elevate her talents to another plateau. Meanwhile, she (and her regular crew of crackerjack jazz virtuosos) continues to do great work with the material of others including Tom Waits, Joni Mitchell, Mose Allison and her hubby. But it is her rendition of Chris Smither's (via Bonnie Raitt) bluesy nugget 'Love Me Like a Man' which shows still another side of Ms. Krall-sexy, ballsy and fun. Elvis, apparently, not only has great taste in music but collaborators, as well.
