Pop music and rock music are often treated as separate genres but the distinction has always been blurred.  Motti Regev argues that pop–rock is best understood as a single musical form defined by the use of electric and electronic instruments, amplification and related techniques. The history of pop–rock extends from the emergence of rock′n′roll in the 1950s to a variety of contemporary fashions and trends – rock, punk, soul, funk, techno, hip hop, indie, metal, pop and many more. This book offers a highly original account of the emergence of pop–rock music as a global phenomenon in which Anglo–American and many other national and ethnic variants interact in complex ways.  Pop–rock is analysed as a prime instance of ′aesthetic cosmopolitanism′ – that is, the gradual formation, in late modernity, of world culture as a single interconnected entity in which different social groupings around the world increasingly share common ground in their aesthetic perceptions, expressive forms and cultural practices. Drawing on a wide array of examples, this path–breaking book will be of great interest to students and scholars in cultural sociology, media and cultural studies as well as the study of popular music.
