That build to the bass was sexy as hell. This is some sick stuff you got, I hope you can finish it soon. :D My only suggestion would be to give the kick drum just a little more punch in the intro, it just feels too soft. I can see though how you would want that for the dynamic change between the intro and the bass, but it's just a bit too soft. Anyway, great work.
Not usually into dubstep, but I really liked this! None of that nonsense with "wubwubwub" triplets. Good balance of momentum and melody.
Looking forward to hearing the full thing :D
Please contact me if you would like to use this in a project. We can discuss the details.
