"How much?" and "why?" are basically the two questions raised by this record. Yes, Planet Mu brings here out a one-track 12" by Starkey for the price of a long player. And yes, the second side is a Serato control one (to be used by DJ using this software), the whole thing is pressed on gray vinyl, and comes with its own fancy sleeve. But still, while "Knob Twiddler" is a really strong Starkey track which shows well how much this artist has progressed recently, I can't help myself but find the whole Serato branding of this record quite lame. I'll get its audio side, but I guess there are people out there who want or need the other one.
