most of James Johnson's music. The Butterfly Chamber is a good one.
Also he teamed up with Alio Die in "Cube 7" and it pretty much fits what you're looking for.
Lately I downloaded Emanuel Errante's Humus download on Somnia label. Though I haven't heard Herion's Out and About, maybe those 2 albums could work.
Not sure if it's your style but I would also go for something like Marconi Union or Erik Wollo, when his guitar playing meshes with ambient (like Emotional Landscapes).
