Halloween-post! The artist is Omnitica, a really good dubstep-artist who often implements d&b in his tracks. I really enjoy listening to his music and he has plenty of good songs. You can go check them out at http://soundcloud.com/omnitica. I highly recommend "Yo!Ho!And a bottle of Bass!" ;-)
If you wanna download the song, the downloadlink is in the description of the youtube-video.
