The Lower Bottoms’ impresario Marcel Diallo has been masterful about bringing Oakland’s past and present together. Little surprise then that he is behind the show “Black Panther: The Cultural Ministry of Emory Douglas” that opens Aug. 22 and runs until Sept. 26 at the Cannery, 1200 Pine St. “We have to have some white walls, sometimes,” Diallo said after Douglas, who served as the Panthers’ minister of culture from 1967 to the 1980s, spoke at the Oakland Museum a couple weeks ago. No pun intended (I commented the show was fancy) I assume, from Diallo, founder of the Black New World and Cornelia Bell’s Black Bottom Gallery, whose walls are not as boomer-style as the Cannery lofts. So just to let you know in advance, an opening night reception will be held at the lofts, 1200 Pine St: A conversation with Emory Douglas, a performance by Diallo & Co. Pluse a special cultural presentation. Prints and books will be available. FMI: 510-451-4661.
