Nerdcore For Life is a documentary, currently in production, about the
Nerdcore hip-hop scene; this is a predominantly American phenomenon, in which members of IT/geek subcultures have embraced hip-hop as a medium, producing beats on computer-based studios, recording raps about topics such as computers, cult sci-fi books/movies and copyright reform, and mostly releasing them as MP3s or via streaming internet radio shows. Some Nerdcore rappers take the hip-hop medium more seriously than others; the approach varies from straight adoption of the rap idiom to talk about issues of geek interest to self-referential parodies of mainstream hip-hop bordering on the Weird Al-esque.
Here is a 4 1/2-minute trailer for the documentary; it seems pretty interesting.
