Saw a post at SHF and this was from amazon.fr:
There is hope that this could be a proper Atmos mix as Bob Mackenzie from Real World Studious involved and had to look at Peter Gabriel-I/O and see same person was listed as one of the ones working on Atmos for that release.
For the 50th anniversary of "The Lamb Lies Down On Broadway", this 4CD + Blu-Ray audio box set offers this flagship Genesis album in an "augmented" version. Benefiting from the involvement of the band members (Tony Banks, Phil Collins, Peter Gabriel, Steve Hackett and Mike Rutherford), this box set allows an in-depth exploration of this opus. It contains:
On CD1 and CD2: the original album remastered in 2024 by Miles Showell at Abbey Road Studios, from the 1974 analog tapes.
On CD3 and CD4: The complete concert "The Lamb Lies Down On Broadway / Live At The Shrine Auditorium", remastered in 2024. Recorded on January 24, 1975, it is presented here for the first time in its entirety since it offers the two encore titles, "Watcher of the Skies" and "The Musical Box".
On the audio Blu-ray: 2 versions of the album, one remastered in 96kHz/24-bit high resolution, and the other in Dolby ATMOS, produced by Bob Mackenzie at Real World Studios under the supervision of Peter Gabriel and Tony Banks.
On a download card: 3 unreleased demos from the legendary Headley Grange sessions (digital bonuses). This card also gives access to the entire audio content of the box set.
This box set also includes a large format 60-page hardback book, the booklet of which was written by Alexis Petridis who interviewed the five members of the band. They tell for the first time since the album's release the story of "The Lamb", from the writing sessions to the concerts. Photos, including some of Armando Gallo and Richard Haines, are also included in this book. In addition, there is the program of the 1975 tour, a reproduction of the original concert ticket and a poster.
