I found a great film about the evolution of dubstep and its protagonists and places. The SRK crew follow people through Croydon, the Big apple record store, the club Fwd, climb house roofs with Heny G from Anti Social Entertainment who explains how pirate radio shows work, visit Sub FM, explain the mastering process, film club nights, meet Mala, Skream, Hatcha, Kode9, Benga, N-Type, the Plastician, Mary Ann Hobbs, and many, many more. Very insightful and entertaining!
