SAN FRANCISCO (CBS SF) — Members of iconic Bay Area band Metallica on Thursday appeared with San Francisco Mayor London Breed at the Chase Center for an official proclamation commemorating the first 40 years of the influential group.

Metallica drummer and co-founder Lars Ulrich and bassist Robert Trujillo appeared onstage with the mayor and Another Planet Entertainment President Gregg Perloff for the press event where the proclamation was made.

Mayor Breed praised the band for its importance to San Francisco and the Bay Area, pointing out that even though they can sell out large venues like the Chase Center where they will be playing their two 40th anniversary shows this Friday and Sunday, the band also maintains its ties to the community by playing much smaller venues like the Independent on Divisadero Street as they did for a surprise concert last September.

“When you talk about San Francisco, you talk about cable cars and then you talk about Metallica,” said Breed. “And on behalf of the City and County of San Francisco, I want to officially declare today Metallica Day.”

Last month, the band announced that in addition to the two sold-out Chase Center concerts, it would be curating a series of “San Francisco Takeover” events to help mark the group’s 40th Anniversary.

The list of associated events will include a free block party in the Mission on Valencia Street between 15th and 17th streets starting at 5 p.m. Thursday. There will also be whiskey tastings, concerts, a film festival featuring Metallica-focused films at the AMC Kabuki and several events involving band photographer Ross Halfin and the release of a new photo book focused on the band’s self-titled 1991 “Black Album.” That effort marked its 30th anniversary this year and recently got a deluxe box set treatment and remastered reissue.
