Musicians have often wanted to change the world. From underground innovators to pop icons, many have believed in the political power of music. Rulers recognise it too. Music has been used to challenge the political and social order—and to prop up the status quo. ‘Sound System’ is the story of one musician’s journey to discover what makes music so powerful. Dave Randall uses his insider’s knowledge of the industry to shed light on the secrets of celebrity, commodification and culture. This is a book of raves, riots and revolution. From Glastonbury Festival to Palestine, The X Factor to Trinidadian Carnival, Randall finds political inspiration across the musical spectrum and poses the question: how can we make music serve the interests of the many, rather than the few? This new edition is updated throughout, including an exploration of the relationship between music and protest against the invasion of Gaza. Randall also dives into new creator trends and considers the potential impact of AI on both artists and industry.
