At the cusp of a new millennium, British electronic music was rapidly changing. Jungle and garage had broken into the mainstream, but were running out of creative gas - what fresh movement would next captivate the underground? On the outer edges of London, a small group of bass lovers had the answer. Through a new strain of subloaded beats that stripped jungle, rave, techno and garage for parts, this scene returned to the dub roots, prizing the fundamentals of soundsystem culture: bass, space and togetherness. They called it dubstep.

In Aftershock: The Seismic Impact of Dubstep, seasoned music writer Lauren Martin charts the origins of one of the 21st century's most innovative music genres in an oral history format. Through the testimonies of its architects and an immersive array of photography, flyers and unseen scene history, Aftershock chronicles the rise of artists like Skream, Mala, Coki, Loefah, Horsepower Productions and Rusko, as well as labels and parties such as Hyperdub, Tempa, DMZ, FWD>> and Skull Disco.

Together, this movement shook the British underground, exploded onto the internet, and, within a decade, had rocked global music at unprecedented scale. Through first-hand storytelling, Aftershock is a testament to how the imagination and persistence of a few can transform culture.
