CB4 is a 1993 American satirical mockumentary black comedy film directed by Tamra Davis and starring Chris Rock. The film follows a fictional rap group named "CB4", named after the prison block in which the group was allegedly formed (Cell Block 4). The movie primarily parodies gangsta rap and the rap group N.W.A, as well as taking inspiration from This Is Spinal Tap. It contains short segments featuring celebrities and musicians such as Halle Berry, Eazy-E, Butthole Surfers, Ice-T, Ice Cube, Flavor Flav, and Shaquille O'Neal.

Plot

Albert Brown, an aspiring rapper and suburban kid who idolizes the gangsta rappers he sees on TV, decides to start a rap group with his friends, Euripides and Otis. Unfortunately, even though all three of them are talented, they have no connections and no image with which they can market themselves.
