It's hard to judge on a thing like originality, so we need to break it down to the basics....are you feelin' it or not? This is a laptop battle, a punk soundclash delivered via a little silver box that's been programed to destroy.
It's not easy to "perform" with a laptop. Each contestant is allowed 1 Midi controller, which allows them to interface with their music software via knobs, faders, buttons, keys, pads, etc. This is their weapon of choice, the way they have chosen to interface with their musical creation...you want to see 'em workin' that shit!
Hooks, builds and breakdowns. Sounds, patterns and movement. How well they are fit together live will be your decision.
Crowd response could be described as how loud the audience cheers for one contestant or the other. Or it could be their reaction to the battle on the dancefloor as the track is played. Perhaps an exodus to the bar? The crowd is like a barometer, it predicts the obvious outcomes, but isn't always right. Other times, there is a contestant with a bunch of fans who are there to be heard. Ultimately, you make the decision. Remember: There are no rematches.
