Singer/pianist Diana Krall breaks new ground interpreting modern standards by Tom Waits, Mose Allison, and Joni Mitchell, as well as compositions by herself and new husband, Elvis Costello. Krall’s piano-jazz cred comes through loudly and clearly on her Count Basie-styled version of the Bonnie Raitt staple ˝Love Me Like a Man˝ (written by folk-bluesman Chris Smither). But it’s the collaborations with her spouse that unearth untapped emotional nuances of her velvet voice; many are reminiscent of Bill Evans’s moody, impressionistic pieces. The title track, ˝Narrow Daylight,˝ ˝Abandoned Masquerade,˝ and ˝I’m Coming Through˝ all deal with love and loss. ˝Departure Bay,˝ a picturesque ode to her hometown of Nanaimo, B.C., proves that this is the start of something big, and that two heads--and hearts--are better than one.
