This book is a revelatory guide to hundreds and hundreds of original 7 record cover sleeve designs - visual artefacts found at the heart of the most radical and anarchistic musical movement of the 20th century. Punk Rock 45 Sound system! is introduced (and co-compiled) by Jon Savage, author of the acclaimed definitive history of punk, England's Dreaming. As well as the encyclopaedic visual imagery featured inside, the book also includes a number of interviews with celebrated designers involved in creating punk's original iconic imagery. The revolutionary do-it-yourself ethic of punk was applied to the aesthetic of design as much as it was to music, and record sleeves acted as lo-fi signifiers of anarchy, style, fashion, politics and more with an urban and suburban invective courtesy of the 1000s of new bands - punk, post-punk, pre-punk, nearly-punk and more - that emerged at the end of the 1970s. This book is an exhaustive, thorough and exciting celebration of the stunning artwork of punk music - everything from the most celebrated and iconic designs through to the stark beauty of the cheapest do-it-yourself lo-fi obscurities.
