I have yet to hear an Atmos demo but am certainly excited for the prospect. Thinking specifically about the (2 or 4) overhead channels, it would seem a no-brainer for movies as there are many ways that sound can come from overhead, but my question is about Atmos music mixes. It would seem that the overhead channels would primarily be for ambience / decay / reverb, and less about discrete musical information, correct? Having musicians seemingly playing all around you (front, back, sides) makes a lot of sense to me but I can't imagine having guitars or percussion or solo voices coming from overhead sounding natural in a music-only format. I wonder when music-only releases start to appear if we as a group will voice our displeasure at "not enough discrete information coming from overhead"? I'm curious as to what others expect will be an "ideal" music mix in, say, 7.1.4.
