She doesn’t need an introduction — Kamaiyah is the driven and lovable ’90s baby who wrote “Why You Always Hatin?” and released a damn-near perfect debut mixtape back in the spring. Today, she shares a new video for “Fuck It Up,” produced by The FADER and directed by Chris Simmons. Made while cruising around High Street in Oakland, its convocation is recited by Shay Diddy of local institution KMEL, and its conclusion finds everyone invited to mob in the parking lot — her childhood Big Money Gang Crew, and hella babies too.
