Examining every aspect of progressive rock - words and music, theatre and politics - Hegarty and Halliwell deftly unpick the tangled threads of tradition and radicalism that make up the genre's tapestry. In addition to shedding vital new light on an often maligned and misunderstood phase in rock's history, this probing and incisive study tracks prog's continued and unexpected reverberations through popular music long after punk had supposedly vanquished and banished it.
