Jazz for relaxation


Could you suggest me a couple of titles (CD)... I'm looking for jazz, most of the time slow, quite, calming, and harmonious enough to relax, if not meditate, on. Piano, double bass, whatever else...
Preferably to be recorded between '90th to present, with extremelly good quality.

Thanks!!

Jazz at the pawnshop, billie holliday, count bassie orch, Diana Krall, Patricia Barber, David Benoit etc...

Vocal: Trio Medieval - Words of the Angel

I like everything on Referencerecording.com from the jazz section as well.

Thanks to you all! I just forgot to mention that I prefer no vocal (not at all, but in this topic), just acoustic.

Marakanetz, I liked your comment. :) Though you like any jazz, I think it's still possible to narrow the results by the criteras provided, not everybode relaxes from just any jazz, some of it may be quite energizing, some nervous... Emotions in music are not always positive...
I would suggest 'Beyond The Missouri Sky' by Pat Matheny and Charlie Haden, both Missouri boys. Two acoustic instruments and very melodic. You should be able to find it at Tower, Barnes & Noble, or Borders.
