Civic Auditorium will be renamed Bill Graham Auditorium in honor of the late rock music promoter who produced more than 100 shows at the hall.The Board of Supervisors unanimously approved the name change on Tuesday. A dedication will be scheduled after the measure passes its second reading next week, said Supervisor Angela Alioto. Graham, who introduced the world to such stars as Janis Joplin, Jefferson Airplane and the Grateful Dead, was killed Oct. 25, 1991, when his helicopter crashed into an electrical tower after a concert at the Concord Pavilion. “We are extremely pleased with the vote,” said Nicholas Clainos, president of Bill Graham Presents. “Bill loved that venue, and it’s fitting to remember him in the context of public assemblage.” The auditorium has been known as Civic Auditorium since it was built 77 years ago. Graham produced shows there by the Who, David Bowie, Carole King, Madonna and Metallica, among others.
