I really like your mix howler, even if finga is trying to no-to-subtly inform you that it is perhaps breaking the rules. I have a Traktor Kontrol S2 which I use to mix 140bpm+ trance. However I am slowly starting to see the light with electro house, which will be a welcome bit of variation in my music diet.
I really do need to practice on the S2 more. Got any videos of yourself in the mix
EDIT: How did you do that stutter effect in the beginning of Avicii - Levels? Did you just loop in and out really quickly or did you map the jog wheels to effects (couldn't think of a better way to phrase this)?
