This is Yes at the height of their creative powers. An essential recording for all progressive collections. This contains just three pieces of music; the epic "Close to the Edge", the heavy rocking of "Siberian Khatru", and the soaring beauty of "And You And I". Bill Bruford left Yes after this to join King Crimson. "Close To The Edge" is broken into various sections. Everything from sound effects to the avant-garde, beautiful vocals; catchy. Wakeman creates some wonderful atmosphere throughout but I especially enjoy the Mellotron and the beautiful church-like organ section. "And You And I" is simple yet dramatic. Again Wakeman's Mellotron, this time mixed with some slide (or lap steel) played by Howe create the perfect music for Anderson's soaring vocals.  "Siberian Khatru" ends the CD and is very heavy - this one rocks. Some nice guitar work from Howe on this one as well. A great opening to say the least. I have never heard anything the band has done since that stands up to this record overall (though they have come close). Essential!
