Chris Rock stars in this rap version of THIS IS SPINAL TAP as Albert, a suburban wannabe rap star who, along with two friends, has tried everything to break into the music business. However, when Albert is mistakes for an undercover cop by a nasty thug named Murphy, he adopts the newly incarcerated Murphy`s persona and christens his rap group CB4, after Murphy`s cell block address. Vowing to glorify violence and disparage women, CB4 are quickly signed to a lucrative record contract. Soon, the band is selling out concerts, and attracts a nerdy documentary filmmaker (Elliott) to chronicle their rise to the top of the charts among the protests of outraged parents and politicians. Fitfully funny and possessing a fine cast of SNL alums as well as cameos from real life rappers like Flavor Flav, Ice Cube, and Ice-T, CB4 is an excellent spoof of the rap music industry.
