Nearly everyone in Progressive Rock Music, musicians and audience alike, are hugely aware of the symbiotic nature of the artwork and the music. After the first few albums, we never got to see the typical "Group Shot" of Yes again. With Genesis, Pink Floyd, Greenslade, and ELP.. the same rarity of such things was pronounced. There were exceptions, usually Live recordings or compilations etc... and of course "Love Beach". By and large, the history of Progressive Rock albums is as much about Paul Whitehead, Roger Dean, Patrick Woodroffe and Storm Thorgerson - even H R Giger as it is about the bands they helped to develop.
