One of my best albums

Fabulous! Far experiments and improvisations of other albums, the English have created here a work of immense, almost a concept album, a rock opera. I saw them on stage at the time, playing note for note the cd. (1975)
Hear now the voice of Dagmar Krause (which has not had the career that she deserved).
I know every note of this album. It is a cry. It is my worship album.
