Late Night Jazz

I like to keep my late night listening sessions simple— my favorite leather chair, a small fire on a cold night, bourbon (neat), and jazz that has a beautiful simplicity. I often reach for Chet Baker: Chet (OJC-087). To me it is relaxed, intimate, uncomplicated. There just seems to be space between the notes, and they just float. I am looking for other suggestions like this. Preferably on vinyl. Thanks.
@cabfiend: I gave Coltrane and Hartman a late night spin.. and it is indeed a good one.  I especially enjoyed Coltrane’s rhythm section — Jones using brushes the whole album, Garrison plucking deep, round notes to go along perfectly with Hartman’s voice. Great recording as well (Impulse AS-40).
How come I never read about audiogon folks listening to organ jazz? Nothing like an organ ballad at night. Dig through any organ album, they all have at least one ballad. But even the up stuff is good after dark.

Ballads by Coltrane is hard to beat for late-night, "wine"-down listening. (The new release from QRP is amazing) But also try Coltrane’s Crescent, one of my personal favorites and Love Letter by Jimmy Heath.
