From the origins of Dub in Jamaican Reggae culture of the early 70s thru to the production and remix techniques of contemporary electronic dance music, Dub Echoes traces the step by step development of a global music culture whose repercussions rank among the most far-reaching ever. Using extremely limited technical means pioneers like King Tubby and Lee Perry laid down musical foundations without which most of today’s music would be unimaginable. In their hands the recording studio became an instrument in its own right, one that opened up a universe of sweeping experiments and founded a global bass-culture that is still steering sound systems in the club scene today. And Dub with its B-sides, sound systems, toasters and MCs is no less an important marker on the road to remix. The film contains numerous interviews with and portraits of the original Jamaican sound pioneers like U Roy, King Jammy, Lee Perry, Sly Dunbar and Bunny Lee, the second generation of Dub producers like Adrian Sherwood and contemporary crossover musicians like Kode9, Roots Manuva and Howie B.
