I have Booka Shade - Dear Future Self in Atmos and it's jaw dropping in terms of imaging. I'd personally prefer more of a song than conventional techno/house (ala Delerium) , but the crazy good imaging makes it infinitely more interesting than it would have been in stereo or even 5.1.
Sounds literally come from every nook and cranny in my 12'x25' room using 17.1 speakers (essentially 7.1.6 plus two sets of matrixed and arrayed speakers for three rows of seating, giving three different perspectives in a 11.1.6 configuration).
That's basically 7.1 with front wides and surround#1 added (former on side wall in front of the first row ~20% into room (ideal would be 25%, but seating interferes) and latter between side surround and rear surround ~75% into the room. Overhead speakers consist of front and rear heights mounted at or on the ceiling at 0% and 100% into the room with top middle at 50% into the room. This gives edge to edge coverage above and below.
I have Lichtmond 4 - The Journey in 3D visuals + Dolby Atmos and it's almost as impressive in imaging terms with instruments and vocals that surround you and even move in circles around the room at times like a clock (Lichtmond 3 - Days of Eternity also does this with Auro-3D instead like the clocks you see on screen). Their music is a bit like Enigma or Delerium meets Pink Floyd.
Clearly, Atmos is ideal for all forms of electronica types of music or something like Pink Floyd, being able to literally surround you with sounds. However, even classical and jazz can benefit from room reflection ambience recorded with something like the dual quad microphones used by the Auro-3D music recordings. You really feel like you're at the actual venue rather than in your home theater room (I think a deadened room works best as it lets the speakers better recreate the original venue instead of mixing it with your own room acoustics). I really felt like I was in the church with the Toccata and Fugue demo, for example (comes with Auro's first demo disc; There's an abridged version on streaming demos you can find online).
Mando Diao's Aelita album is also awesome in Auro-3D using discrete imaging mixed with ambience at different height levels to envelop you (less crazy imaging than Booka Shade or Lichtmond, but far more than just ambience.
Really it's a shame there isn't more content for immersive formats (I don't think I've seen any real DTS:X music offerings yet at all, even though I own 40 movies in DTS:X). I think part if the problem is getting more people to do an Atmos/X or Auro-3D setup. Most still don't even have 5.1 for movies let alone a quality Atmos type setup with speakers of really competent music quality. I went with PSB speakers as they are extremely neutral with +/- 1.5 dB frequency response (I get right about +/- 3dB overall room response with REW for the MLP with +/- 2dB for bass and much of the midrange, which is excellent, IMO). I find myself listening to music in my home theater a lot more often, even in stereo (upstairs system uses Carver AL-III 6' tall dipole ribbon speakers with custom active crossovers and 2x Carver 350W amps and a Carver C-5 Sonic Holography preamp so I'm used to pretty good stereo sound).
