Red Bull Music Academy have got a great series of mini-documentaries going on at the moment, and today they’ve released the third installment which looks at hip-hop, and more specifically the micro-genre of “cloud rap.” RBMA talk to some of the major players in the movement, including Main Attrakionz and SpaceGhostPurrp, as well as journalists and assorted talking heads.

If you haven’t already, make sure you take a look at the first two episodes in the series, one on modern R&B (featuring Miguel and How To Dress Well) and the other on dubstep/bass music (featuring Mount Kimbie, Bondax and Deadboy).
