Your Ethnomusicologiquement

Unlike the great works of Aymeric Leroy, this book focuses on the sociological aspect and "ethnological" the main protagonists of the English progressive rock (social classes, origins, etc.).
Without draw a portrait thurifer and / or subjective kind of (thing could a book written by an enthusiast), this book allows us to study progressive rock through a sociological prism.

Its originality and approach, I highly recommend it for fans, the curious, nostalgic, sociologists see;)
