The open-source MC BY Chris Bilton December 16, 2008 13:12 In the world of hip-hop, sometimes the price tag on a pimped-out Escalade or a pair of custom Skytops is as important as a clever internal rhyme or a chorus hook. And in a genre where bling reigns supreme, the most unlikely rapper would be one that's doing it for free. But that's precisely how Proteus (a.k.a. Aaron Campbell) is making his mark: as the self-proclaimed world's first open-source MC. Of course, Campbell is working on the outer edges of hip-hop — far from the temptations of slick production and Auto-Tune trendiness. His raps are intended for sub-subgenres like underground IDM and modern breakcore. But despite working some relatively obscure genres, there appears to be a wealth of artists eager to take him up on his open-source offer. In the three years he's been making his stuff available, he's accumulated over 300 songs worth of collaborations. After Campbell ended his successful stint as the DJ behind local dance night Altered Beats, he wanted to start making the kind of music he was spinning. With the help of a team of cyber-junkies — most of whom started coming to his shows to find out just who was this Proteus character playing their flavour of glitchy dance tunes — the Altered Beats website was assembled for Campbell to begin uploading raps that he recorded. Basically, he just posts .ftp files of vocal tracks to be downloaded by anyone interested in pairing them with their own productions. In return for using his voice, he asks only that people send him a copy of the finished product so he can post them on the site as well. As a method of collaboration, this open-source approach is essentially the polar opposite of hip-hop's high-profile duets, which often demand the diplomatic talents of publicists, managers and lawyers more than any actual musical ability. And when it comes to intellectual property rights and illegal downloading paranoia, Proteus is sort of like the anti-Metallica. Plus,
