^ Alex Nut and the Eglo stuff I often associate with jazzy vibes. It's not my favorite stuff in the world but I enjoy listening to his Rinse show every so often.
Edit: so artist/producer wise I guess that would mean folks like Mizz Beats, Fatima, Floating Points, Funkineven. Some things by people like Sbtrkt, Shy One, Jessie Ware, Sampha I often put together with them in my head, they've got a similar feel. I guess only a certain amount of their output explicitly uses elements from jazz, but they've got those kind of vibes you're describing - laid-back, bumpy, somewhat sophisticated, colour/texture and some acoustic/live instrument feel at times. I sometimes find similar kind of vibes in the stuff the Anti-Social guys do, but I'm sure you know them already.
Sorry for the lists, just typing off the top of my head here.
Edit edit: Basically I guess I'm thinking of the folks who do 'live PA' sort of sets at Boiler Room (and that's not meant as a par before anyone starts...).
