Some more things that I think haven't been mentioned:
Find some Art Tatum. I don't know what to recommend (someone here will know). The records I have of his stuff were picked up from a car boot sale for 50p a shot. Everything i've heard of his is staggeringly good.
EST are good, modern and different - Tuesday Wonderland is nice. It's good to hear modern production techniques, overdriven guitar, synths etc appear in jazz.
Bill Wells. Try 'Also in White' by the Bill Wells Trio. Modern, simple, humourous. I also really like 'Osaka Bridge' recorded with Maher Shalal Hash Baz which is difficult to describe, as the playing is purposely loose and often wrong with duff notes. You'll either find it annoyingly amateur or insightful. The missus struggles with the dodgy tuning though but thankfully i'm immune to this.
Oh, and you need something with vibes, which says Milt Jackson. I suggest the Modern Jazz Quartet, I always like their 'plays Gershwin' album. Simple playing, lovely sounds wafting around the house. Milt Jackson is a real hero, and John Lewis plays so few notes on the piano he makes it sound easy (it's not). What's not to like?
