I need help making sense of all this. I've got physical copies of the stereo mixes and access to Atmos on Tidal. I've also purchased every BluRay set by the Fabs. There are seven different years referenced as mix years. Please help me understand.
2015 - These are the "1+" mixes? Stereo I understand, but where did the Atmos mixes come from? If I remember correctly the 5.1 mixes on the BluRay were done by playing the stereo mixes in Studio 2 at one end of the room and then recording the "rears" at the other end. So not really a 5.1 mix. Was the Atmos based on these faux 5.1 mixes?
2017 - The Sgt Pepper 50th. Giles did an original Atmos mix for large theater presentations. Did he remix it for home consumption as promised?
2018 - The "White Album" 50th. Again we had stereo mixes. Where did the Atmos come from?
2019 - Abbey Road 50th. OK, stereo and Atmos on the BluRay. No questions here.
2021 - Let It Be 50th. Ditto as Abbey Road.
2022 - Revolver. No questions. New stereo and Atmos mixes released this year on streaming only.
2023 - All other material remixed this year, stereo and Atmos. Again, no questions here.
So in conclusion, where (or should I say, when) were the Atmos mixes done for 2015, 2017 and 2018 marked mixes?
