A really nice recent find is Somnia by Grey Davis. Six tracks of quiet atmospherics and synthy drones. The shortest track clocks in at 4:02, and track 4, Campestral (version 2) is over 22 minutes in length. The record is full of nice long tracks that are really quite good at fading into the background.
I picked up a few other records from Davis recently as well, and they're quite good. I'll likely have something to say about them around here shortly. In the meantime, have a listen to his work, it's really top-notch stuff.
