Chris - You are exactly right with regards to the recent Dirk Serries albums. I like his return to vidnaObmana style ambience. I love ambient guitar so these two releases are right in my wheelhouse. I actually didn't know about "Disorientation Flow" until I saw your post, so thanks for the heads up.
Other recent spins:
Alva Noto | Xerrox vol.3 - Chris, you are right on this one too. Some spectacular cuts on it & overall one of my favorite ambient albums of the year.
Marconi Union | Departures - Good spacey ambient from Marconi Union who never disappoint.
Steve Roach | Skeleton Keys - I haven't really liked Roach's berlin school stuff in a long time but this one worked for me, I like it a lot.
David Cross & Robert Fripp | Starless Starlight - A collection of tracks that play off the song "Starless" from the King Crimson album Red. The tunes are essentially ambient violin, loops & electronics with the occasional guitar noodling from Fripp. I love the original track so much that it is great to hear this new take on that theme.
