Roger Waters is in fact not Pink Floyd ...

The good first: In terms of content, this work is a masterpiece. Musically, it proves, however, that Roger Waters, the musical mastermind Pink Floyd's was not, as many believe. The album looks really artificial, although the sound effects are in a sensitive, expressive and delicate sound structures -As of the Floyd's hope gewohnt-, but it will be hopelessly disappointed. Musically the Devison Bell the other PF Mitgleder is so much better and more expressive.
For those who believe, "the Wall" would be a musical solo effort Water's: so stehts Although in the credits, but in fact is Gilmour (MUSICAL) COMPLETELY responsible for the following pieces: The thin ice, another brick in the wall pt1 + 2, Mother , Good Bye Blue Sky, Hey You, Comfortably Numb and Run Like Hell. 5 more pieces also come not from Waters alone but by Ezrin / Kamen. On the albums before wars not much different.
So therefore can easily explain why this album is not nearly as acts like the Pink Floyd concept albums: Waters can write great lyrics, but the music lacks unlike Gilmour and Wright very much.
