Created in the late 60s, fashionable in the early 70s, hated in the late 70s, and ridiculed in the 80s, the rise, fall and rise again of Progressive Rock is a colourful and eventful story. However, many of the genre's main protagonists - Genesis, Yes, Pink Floyd and ELP - remain as popular today as ever, while lesser-known names like Camel, Caravan, Renaissance, Van Der Graaf Generator and Gentle Giant still retain cult status. "Prog" expert Stephen Lambe guides the reader through the early years as the music developed out of the late 60s British Progressive Music boom into its own genre, and reached full maturity with classic albums like Yes's "Close to the Edge" and Genesis' "Selling England By the Pound" in the early 70s.
