10 Best Progressive Rock Albums Of All Time

Drummer Bill Bruford goes out with a bang here in Yes' fifth (and best) LP.

Before jumping ship to King Crimson, Bruford put in the wildest, unwieldiest showing of his career in an album that has had listeners scratching their heads for decades. Look no further than the incomprehensible 'Siberian Khatru', the 'Twin Peaks' of prog rock when it comes to inciting confused discussion and theories among fans.

The titular track clocks in at a whopping 18 minutes and showcases the group at their most ambitious. Inspired by everything from Hermann Hesse's 1922 spiritualist novel 'Siddartha' to 'The Lord of the Rings', it's a one of a kind, four-part centrepiece to this adventurous LP.

Jon Anderson's vocals are as high-pitched as ever, providing a maddened energy throughout the proceedings. There's also Steve Howe's sitar work to consider; his eclectic use of the instrument with the more conventional guitar provides a refined blend of riffs and solos to enjoy.

The 10-minute 'And You and I' delivers more high concept goods with some long form lyrical storytelling over four conceptual parts. Howe's 12-string acoustic guitar provides an atmospheric backdrop to this increasingly apocalyptic epic. At just (technically) three songs, 'Close to the Edge' might look a little underwhelming on paper. Upon listening, however, one quickly realises this LP is a confronting adventure through the fantastical elements of the subconscious. Each track plays out like several colourful songs in one, making this standout LP all the more impressive.
