One of the side effects of the craze for collaborations is that when a rapper starts blowing up they can be inescapable, showing up on tracks alongside possibly dozens of producers and rappers looking to catch some of their reflected shine. For a particularly popular rapper with a robust work ethic this can mean way too many tracks for anyone but the most obsessive fan to keep up with.
For instance Danny Brown, whose eccentric talents resulted in a plethora of guest appearances in 2012. One of them was a team-up with British dance-music duo Evil Nine called "The Black Brad Pitt" (presumably a reference to a line from Jay-Z's version of Panjabi MC's "Mundian To Bach Ke") that came out back in August and that I had no idea even existed until its video debuted earlier today. Kinda wish I had caught that one earlier, but hearing Danny Brown's typically nasty flow for the first time while watching a guy dancing sinuously in a jungle and another guy dressed in an African-dicatator-ish outfit was pretty enjoyable.
*If you are at all interested in Future, or were just wondering why people are freaking out so intensely over him, do yourself a favor and read Rob Harvilla's essay on the man who he says "uses Auto-Tune the way Picasso used nude women." It's really good and somehow made me like Future even more than I already did, which was a whole lot.
