I've always liked Krall and Bennett individually. What surprised me most, was that I liked the Bennett/Gaga CD more than this one. I think it's because I'm used to Krall always doing pop/jazz/standards, and Gaga, away from the outlandish outfits, is a remarkable singer and this was her first foray into the standards/jazz genre.
PS - I did not like the latest version of "A Star is Born" other than the dog.
Disclaimer: my parents owned a music & appliance store, and I grew up on the American Songbook (as it's referred to) as well as their records of the big bands of the 30s & 40s. Beatles were ok, not fond of Mick Jagger, I think I have every recording by Ella, the Count, the Duke, Aretha, and to me, The King is Nat, not Elvis.
