Sifting through the heap of dubstep which has formed on the landscape, I've managed to find a few artists worth mentioning. Kill The Noise bring some interesting things to the mix, as well as Excision and Subvert, who I learned about when they did a remix of one of my favorite songs of all time, "Zombie" by The Cranberries.
One of my more recent finds is a group called Broken Note which manages to appeal to my industrial inner-workings. They have an extremely heavy sound, with drum-and-bass-style rhythms that break up the usual formula of dubstep (step 1: build it, step 2: drop it). Their video has some great, hypnotic imagery:
On the other end of the production spectrum, there's a guy called ThePeteBox who is doing some quality stuff in the world of beat-boxing/looping. He has an album coming out April 11th called Future Loops which I might be checking out. Here's him doing a mind-blowing, one-man cover of "Where is My Mind?" by The Pixies, the song you might know from the final frames of the Fight Club film.
