A sputum Roger Waters (supporting less external pressure) on a overexcited in the first row at a concert of Floyd at the Montreal Olympic Stadium for the promotion of Animals in 1977 (the night, Gilmour n is not back on stage when recalling to show his disapproval of a public undisciplined), gave its author the idea of this anthology album. The concept of The Wall (11th album) was born from Waters, namely build a wall between the group and the public to protect themselves. The demo of Waters, inaudible by hand, was submitted to the other members who adopted it. It took eight months, four different studios, a group the edge of a financial abyss and return to reason Waters (who had fired Rick Wright during this recording and which will officially reinstated Pink Floyd in 1994) to record this disc, released November 30, 1979 and contains the heavier songs, the hardest of the group. The Wall is not a rock opera or a concept album or not even a musical oratorio: it is an amalgam of all that. One thing is certain: Pink Floyd dropped its psychedelic side which makes accessible its 26 songs (23 and 3 signed Waters Gilmour / Waters which Comfortably Numb and Run Like Hell) that revolve around the theme of confinement. The tone is sometimes rock, sometimes more quiet and dark, sometimes ballad or disco (Another Brick In The Wall II) with shouts, explosions, echoes ... No complaints. It is well written, well composed, poignant, coherent .The album cover is sober and is a pristine white wall, wall symbol of non-communication. Indispensable!
