I only have 5.1 so I have no idea about the Atmos-ification. I just know this: the Raw mixes put me in the room like nothing else I know. It’s something about the unvarnished performances and what I can only describe as “sympathetic” mixing that tastefully arranges the vocals, instruments, patter, and control room chatter in a way that delivers peak verisimilitude.
My personal go to test tracks are Crippled Inside, take 2 on the Raw album (track 12) and Oh My Love’s ethereal isolated vocal on the Elements album (track 7) or the lovely instrumental Jealous Guy highlighting Nicky Hopkins piano (track 3). I only wish we had the instrumental How Do You Sleep!
This isn’t a backhanded critique of the “underdubbed” or Giles Martin mixes. For me, these two discs are a sort of pea, having been mixed before the Atmos gold rush. Along with the recent Who’s Next | Life House, it’s the intensely rare release where we get dedicated, thoughtful surround mixes for the work product. It’s a shame the physical release (like the White Album and Sgt. Pepper) doesn’t have Atmos but the 5.1 is excellent — and that box’s visual graphs illustrating the each track’s mix approach is the toppermost of the poppermost.
