Since the emergence of rock¿n¿roll in the early 1950s, there have been a number of live musical performances that became hugely influential in the way they shaped the subsequent trajectory and development of popular music. Each, in its own way, introduced new styles, confronted existing practices, shifted accepted definitions, and provided templates for others to follow. Performance And Popular Music explores these processes by focusing on some of the specific occasions when such transformations occurred. An international array of scholars reveal that it is through the dynamics of performance - and the interaction between performer and audience - that patterns of musical change and innovation can best be recognised.
