Compared with the Dark Side cabinets and wish, that of The Wall fully deserves the mention "Immersion". In addition to the undeniable masterpiece that is the album, there is also his stage during which completes the work studio. It noted the significant contribution of Wright on keyboards. But the best surprise comes from the two CDs containing the famous demo tapes that Waters had to listen to the group but also reworked demos in the studio. It is a total immersion in the great work of Waters. These demos have documentary value because they provide a fascinating insight into what may be the work of his studio and finds its infancy. More importantly, some versions could act as alternative versions so they are good as is! In short, a delight for the floydophile collector. Only one regret though: during the remarkable story of the genesis of the album, you can see quite a few excerpts from a concert The Wall (the Nassau Coliseum I think) ... Why not have made a DVD of the entire show? Too bad. Perhaps they have set aside for a future release ... Fingers crossed.
