Break out a little bit, especially if you have a good stereo system. Try "John Coltrane and Johnny Hartman" and "Ballads" by John Coltrane.
Also:
Bob Dylan - Nashville Skyline
Art Garfunkel - Angel Clare
Janis Joplin - Pearl
Jerry Mulligan/Thelonius Monk - Mulligan Meets Monk (best recorded sound quality of Monk's piano I've heard)
None of these are new but they aren't old, either. They are timeless.
