If you enjoy Diana Krall, try her "When I Look In Your Eyes" DVD-A. It's a wonderful mix and mastering job. I also echo Steve's (What Furrer's) suggestion of "Swingin' For The Fences."
Here are some suggestions for places to look for them.
DISCLAIMER - In no way should these be considered"recommendations" I have little or no experience with any of them. They are just places I have picked up from forums and searches. Hopefully, others here, who have had experience with any or all of them, will offer their evaluations.
