If, like the vast majority of music listeners, you’re unfamiliar with the term “nerdcore,” then you’re in luck. Nerdcore Rising, an engrossing documentary directed by Negin Farsad, will answer any and all questions you may have about nerdcore, a relatively new hip-hop genre made by and for nerds (e.g., computer nerds, gaming nerds, and pop culture nerds). Farsad tackles nerdcore from various vantage points, interviewing hip-hop names like Prince Paul and J. Live, outside-the-hip-hop-box names like comedian Brian Posehn, singer/comedian ‘Weird Al’ Yankovic and Jello Biafra, the former lead singer of the Dead Kennedys, a post-punk rock band that had its heyday in the late 1970s through the mid 1980s, and closer to the hearts of nerdcore fans everywhere, MC Chris, MC Lars, MC Router, and Optimus Rhyme. Who? Exactly.
