It wasn't just clothes and hair that changed as the 1960s progressed – social awareness crept into youth culture and music ceased to be simply about dancing. A counter-culture gradually emerged, and rock 'n' roll was its defining feature. Pop music broadened beyond the traditional guitar-bass-drum format and started to experiment with new sounds. Musicianship reached unsurpassable levels, and for a brief, glorious time, genuinely experimental music coincided with the popular taste. The explosion of imagination and ambition that characterised the psychedelic movement of the late 1960s stretched the possibilities of the pop song to their limits. Never before or since were so many classic albums made in such a short time. Psychedelia is the most colourful, detailed and authoritative guide to these albums ever published. One hundred of them are evaluated here, using contemporary reviews, rare photographs and interviews, accompanied by a plethora of iconic images and reproductions of cover artwork.
