Musicians have often wanted to change the world. From underground innovators to pop icons, many have believed in the political power of music. Rulers recognize it, too. Music has been used to challenge the political and social order--and to prop up the status quo.

Sound System is a musician's journey to discover what makes music powerful. Dave Randall uses his insider knowledge of the industry to shed light on the secrets of celebrity, commodification, and culture.

This is a book about raves, riots, and revolution. From the Glastonbury Festival to Palestine, The X Factor to the Trinidadian Carnival, Randall finds political inspiration across the musical spectrum. He asks: How can we make music serve the interests of the many rather than the few?

This new edition is updated throughout, including exploring the relationship between music and protest against the invasion of Gaza. Randall also explores new creator trends and considers the potential impact of AI on artists and the industry.
