Stephen Walking is a Dubstep revolution. Heard to be combining elements of metals famous approaches to drum laden structure and uses of distortion within dubstep makes for a very different artist and listen among other musicians, he isnt afraid to break the mould. he often unleashes very short "albums" with 3 or 4 songs, examples of Zombie Union EP and Seven Sages EP. most of Stephen Walking's explosive works can be found on his Bandcamp page http://stephenwalking.bandcamp.com/ he has had some success with Monstercatmedia on youtube
It appears he started sometime during 2011.
