Yesterday's song by Exivious, "Deeply Woven", is exactly the kind of thing I'm talking about, but you don't have to be all jazzy and heavy to get my attention. Tides From Nebula have done the same thing with their slow-burn, atmospheric post-rock. They're not doing anything especially new or noteworthy (there's that recurring iteration vs. innovation thing, eh?) but I still like what I'm hearing.
Check out the track "Only With Presence" from their brand speaking new record Eternal Movement and see if you also like what I'm hearing. And don't you dare point out the resemblance between this song and Russian Circles' "Malko". I heard it too. Can't have too much of a good thing, right?
