Readers' Poll: Your Favorite Prog Rock Albums of All Time

The songs on Yes' 1972 LP are so long they only managed to squeeze three of them onto the thing. Thankfully, they are three of the very best Yes songs. The title track is an 18:43 album-length song divided into four parts. "And You and I" clocks in at a mere 10:08, while the closer, "Siberian Khatru," is one of the proggiest songs ever, both in name and musical content. This masterpiece marked the end of Bill Bruford's initial tenure in Yes, and despite the great work that followed, they never quite recaptured the magic of this period. The band is now going through a pretty bad period, changing lead singers and keyboardists with alarming regularity.
