English director Isaac Julien is our guest tonight and Thursday. Julien is in Berkeley for a week-long residency at Cal, sponsored by the Film Studies Program, Graduate Film Studies Group, Journalism Department, PFA, and the Townsend Center for the Humanities. "A great documentary you probably won't see on MTV anytime soon."-Village Voice Darker Side of Black "undresses hip-hop and dancehall culture machismo," in the words of Village Voice critic James Hannaham. The film focuses on issues raised by Jamaican ragga musician Buju Banton's song "Boom Bye Bye" which advocated shooting homosexuals, and by Jamaican dancehall star Shabba Ranks who seconds that emotion. Interviews with observers of the scene, ranging from former Jamaican Prime Minister Michael Manley and cultural scholar Cornell West to bible-thumping Ranks himself, contribute to Julien's sharp, sometimes wry analysis. At issue is what West calls "an attempt to police black folk into a homogeneous blob"-but what are the roots of that black authoritarianism, clothed as assertion? "It's not me you want to kill, but yourself that you see in me" is only one theory.
