I disagree. Here's what is known to exist and could be included: Animals (2011 Remaster) Animals (1977 Quad mix) Animals (early studio versions from 1976) Live soundboard recording of a complete 1977 show (the band recorded every show on a Nagra via the soundboard) Animals (Needle-drop of original UK vinyl release) High resolution version could also be included. Perhaps even a 5.1 mix but this is unlikely with everything that Guthrie has on his plate right now. Here's a brief review I wrote of the recently leaked work-in-progress studio tracks... Originally appearing on a bootleg LP titled “The Extraction Tapes,” these recordings feature early studio versions of songs from the “Animals” album. These are not demos (and it’s still unknown if demos were ever made for these songs), if they were they would have been recorded back in 1974 as “Raving & Drooling” and “Gotta Be Crazy.” These studio recordings were made somewhere between April and December of 1976 when the band was at Brittania Row recording the album. Early versions of “Sheep” and “Dogs” were performed live on the 1974 and 1975 tours, continuing to be developed even after being scrapped for the “Wish You Were Here” album. What we have here are early studio versions of the songs around the time that the "Animals" concept fell into place. "Dogs" is now sung almost entirely by Roger in his own unique style, an interesting alternative to Gilmour's vocals. I like Roger's take on this a lot but I’m also glad that the first part of the song was ultimately sung by David, highlighting how vital both of these artist's voices were in portraying the Pink Floyd sound. With Gilmour singing most of this song on the recent tours it makes one wonder if there was a conflict in regards to who would end up singing this on the album. The lyrics and structure of this take fall somewhere between the live versions and final studio recording. Missing and alternative guitar solos and keyboard parts will be obvious to anyone familiar with this track. Also absent is the "stone, stone, stone..." sequence as this version awkwardly segues back to the opening guitar riff just at it did during live performances. And for anyone who ever wondered what happened to the missing closing lyrics that appeared on the original LP sleeve but were never recorded for the album well here they are! Who was fitted by bridle and bit? Who was given a seat in the stand? Who was forcing his way to the rain? This take of "Sheep" is actually closer to "Raving & Drooling" and is still sung with the original lyrics. The sections that haven't been written yet serve to highlight the great musicianship of the band, especially Gilmour's incendiary guitar playing. Wright's jazzy organ solo is absent from the opening of the song which makes this sound like a retread of the "psalm" sequence (which is missing The Lord’s Prayer), coming off like a light version of "One of These Days." Waters vocal delivery (and screaming) is even more venomous than on the official studio recording. The versions of both of these songs provide an amazing missing link between the live and official studio recordings. "Pigs" is very close to the officially released version. After fully realizing the "Animals" concept for this album Waters penned "Pigs (3 Different Ones)" while working on the other 2 songs. It makes one wonder how close the initial recordings of this track were to the final version to begin with. Obviously missing here are some of Gilmour’s best work, yet to be recorded, especially the blazing guitar part that closes this song. With the widespread sharing of these recordings on the 37th anniversary of the release of “Animals” fans can finally start to piece together their own Immersion set… marbles, scarfs and other crap are optional.
