Sorry for the delay in my response Lovinthehd & others.
I have only a couple of immersive concert disks (hence the Thread) with two in Atmos:
Roger Waters: The Wall
INXS - Live Baby Live
And a quirky Blues Brothers Movie in DTS-X. I bought this in 4K mostly just for the Tunes.
(Note - I edited the title of this Thread to include DTS-X as that may get more responses - Thanks)
I'm struggling to define which disk I like better as all are okay, but sound wise - nothing stands out to make it my pick as superior over the others, or for that matter an up-mixed normal Blu-ray Concert disk.
Of course a lot has to do with - do I like the music up front. The Wall has maybe 2 tunes in it, but the rest of the disk doesn't get there for me. The INXS concert is a technological achievement on the video front, but not so much on the sound. I'm really only familiar with a couple of their tunes as well, and it's probably better than The Wall. It's been ages since I played The Wall, so maybe I should re-visit it.
Maybe I'm expecting a "wow" moment where the sound just engulfs you more than say the typical 5.1 HD codec experience with the up-mixer engaged.
I have been listening to a few "of the Live at Montreux series" and some are incredible performances which the up-mixer treats well. I haven't heard any of of Steven Wilson's work. Can you suggest a disk or two?
I need to come up with some new ones as I typically put Concert Disks on the top of my Christmas wish list. I'll see if I can check out
Imagine Dragons, Smoke & Mirrors Live.
Thanks for the tips to date.
