This is a fascinating video I encountered online. I'm a huge Lee "Scratch" Perry fan. He revolutionized the dub concept with his recording and mixing techniques with Reggae music. Incredible.
Only lately have I been dabbling into the world of Dubstep, which is considerably different with it's electronic influences. Obviously, though, there is a link in between the two styles.
This video does a great job of relating the origins of the two styles and includes performances and music from Lee Perry, a brief interview with Dubstep monster Rusko, as well as Jahdan performing with Major Lazer (Diplo and Switch's electronic dub/reggae inspired club collaboration.)
Here is Lee Perry's "Blackboard Jungle:" From Dub to Dubstep mini documentary.
