Straight outta Detroit, which he refers to as "the bankrupt city," comedian Brandon T. Jackson started performing when he was only 14 years old. He's had roles in numerous films since then; he had a significant role in the terrific comedy Tropic Thunder that helped launch his acting career. Jackson, who relies on urban slang and makes references to racial stereotypes in his routines, performs tonight at 7:30 at the Improv, where he has shows scheduled through Sunday. Tickets are $20.
