It’s hard to put in context just how hot the band known as Yes were come 1972’s Close to the Edge, except just to say that a song as wired, as wild, as complex, as challenging, as virtuous as Siberian Khatru was pretty much required listening for anyone who was even half-serious about staying in touch with the zeitgeist. “I know where Siberia is. I have no idea what a Khatru is. Except to say it must have something to do with reaching but not quite grasping the essence of all our striving, our yearning, our dreams – the Grail itself, holy and unfathomable. But careful way out there, you don’t want to fall off. The edge, that is. Tread lightly. Enjoy the view.” (Philip Random)
