The British Invasion & The Kinks.
 
Plus not specially art-related but very interesting information about a totally heavy electric rock 'n roll band that produced a cataclysmic wall of sound unlike anything that had ever been heard in rock before and strangely enough, they made their initial reputation as Avant-Gardists:The Kinks
Ray Davies of The Kinks, english Rock & Roll's loyal advocate of the little working people. His brother Dave Davies, author of You Really Got Me, which set the whole ball rolling... and I claim that was the beginning of hard rock (and heavy metal later)!
