Uneven, IMO, but enough works here for me to call it "promising"--ironic word, I know, for an artist as established as Krall. I agree with RonF that "Narrow Daylight" is a highlight, and it's too bad that they didn't include "I'll Never Be the Same" on the American edition. "Almost Blue" is another track that worked quite well for my ears.
I'll have to re-listen to the Cole tribute; it's what turned me off from Diana Krall, but that was many years ago, and maybe I'd hear it differently now.
