Interesting fact: deadmau5 apparently doesn't mix his shit live. Instead he pre-mixes it, then spends the rest of the night playing solitaire or minecraft, and posting on /mu/. Photographic evidence
Yeah... alot of DJ's do that. Also, it has been discussed here before that Deadmau5 isn't a DJ, he produces the music, but also plays it live, because he can, as do many of the producers I listen to.
All of dubstep is made by one machine. Specifically, a machine in the middle of East Texas, with an off centre barrel. This causes it to grind against the housing producing the terrible tearing noise common to dub step. Different loads of sand and gravel can alter the tone of the drum, producing different bass sounds, while the whine of the fan belt that drives the drum can be altered using different kinds of leather and hosiery, producing different "melodies". The number one dubstep hit of all time involved one part Saharan sand and two parts gravel from the beach at Dover. The melody was provided by a strip of denim from an old pair of jeans for the fan belt. It remained on top of the dubstep charts for fourteen consecutive weeks and is considered by many to be the first true classic of dubstep, and set a new standard for machine-noise. The man who organised the mix is unknown, appearing only briefly at the site, now commonly referred to as "the noise cauldron", but anecdotal evidence suggests it was, in fact, the ghost of robot Mozart, Mozartron, who had traveled back in time to create and make popular the very genre of music he would later be built to perfect.
