Vicki Wolf, longtime director of Sushi, San Diego’s leading cutting-edge performance venue, has resigned. Wolf’s departure, which is said to be motivated by “personal reasons,” leaves Sushi “artistically rudderless at a crucial point in its 24-year history. Sushi’s home, the distinctive and historically designated Carnation Building, has been sold to housing developers who plan to build high-rise condominiums on the footprint where artists now do their work.”
