Brian's first recurring role was on "Knots Landing," and from there it was just one more step to his career-making turn as David Silver on "Beverly Hills, 90210." (He was the only cast member actually of high-school age.) His real-life passion for music influenced his character, who became a DJ and a rapper. Since "90210," Brian's had regular roles in the sitcom "Freddie" (with Freddie Prinze Jr.) and U.K. teen drama "Stacey Stone." He's also guested on shows like "Sabrina the Teenage Witch," "CSI," and "Terminator: The Sarah Connor Chronicles." But music, especially hip-hop, takes up a lot of his time: He has his own production company and music studio.
