It often saddens me that this line-up of Yes were only around for this one album, I realise that this is an out-of-the-norm-view (most Yes fans prefering the key-work of Wakeman) but the music that is put down on this suberb album is out of this world.
To me this is one of the rougher Yes albums, the technology needed to create the progressive complexity of the music was a year of so down the line, but the fact that the band pushed the studio to the limit gives it the charm that other albums seem to lack. The result is a hardened and brash sound, no smooth egdes, Howe's guitars are scratchy, Squire's bass sounds like someone melodically scraping a nail along a saw, Bruford's drums having the complexity of the likes of Alex Acuna, but still with that vintage 70s sound.
Although this is possibly not as well recieved or liked as "Close To The Edge", probably because it does not have anything of epic proportions on it, this is still good enough to be classic and naive enough to be charming.
"Yours Is No Disgrace" and "Starship Trooper" are the two obvious choices for best songs, but there is also the ballardesq-come-bop-rock of "I've Seen All Good People", a classic by my recogning as well as the chilled out acoustic solo of "The Clap". This song must not be confused for an album filler, if the listener stops to listen to it fully then they will discover that it is quite good.
Although this album was released a full 10 years before I was born I still think that it is a landmark of both contemporary and popular music. If you only buy 1 Yes album buy this, you will not regret it.
