He mixes everything live, and has a lot more music to sort through than with records because of a computer's storage capacity. I'd say his job may be more difficult than a turntable guy because of that. Not to mention, Gillis usually sets up in a place where the crowd is all around him. So he not only has to mix live, he has to mix live within a few feet/inches of his fans. I'm just surprised he doesn't use an Apple.
