Black tie will meet black leather as the San Francisco Symphony joins Metallica on Sept. 6 to break in the new home of the Golden State Warriors in Mission Bay.

The classical musicians and classic rockers will be the first acts to perform — yes, together — at Chase Center, the new arena that will serve as home to the NBA team in the fall, Warriors officials announced Monday, March 18, at a news conference hosted just outside of the venue attended by Metallica’s Lars Ulrich and James Hetfield, San Francisco Symphony Music Director Michael Tilson Thomas, Warriors owner Joe Lacob, Warriors President and Chief Operating Officer Rick Welts, and San Francisco Mayor London Breed.

“We wanted to do something unique to the Bay Area,” Welts said at the announcement, “something that would happen only here and nowhere else in the world.”

The pairing is not as odd as it sounds.

The concert, which will be conducted by Thomas and Edwin Outwater, marks the 20th anniversary of Metallica’s first performance with the San Francisco Symphony at the Berkeley Community Theater in 1999, which yielded the live album “S&M.” That concert was conducted by the late Michael Kamen.

Billed “S&M2,” this will mark the only date commemorating the occasion.

In addition to the material the groups performed at the first concert, they will also incorporate renditions of Metallica songs written and released since the original “S&M,” with new orchestral charts by Bruce Coughlin.

“It’s a beautiful opportunity,” Hetfield said at the half-hour news conference. “We’re super proud that after 38 years there’s still cool things on the horizon for us.”

Tickets for the concert go on sale at 10 a.m. Friday, March 22, at chasecenter.com. Metallica Fan Club members will be allowed to access them via an exclusive presale at 9 a.m. Tuesday, March 19, and there will also be a presale for Chase cardholders at noon that day.

“We’re not just a sports team anymore,” Lacob said at Monday’s announcement. We now are an entertainment organization – and we want to be just as good at that as we have been at the sports side of things. We want to deliver world-class acts for all right here at this venue for decades to come. And we intend to do that.”

Representatives from powerhouse concert promotion companies LiveNation and Another Planet Entertainment, who are co-presenting the Metallica and Symphony concert, were also present.

The two groups — both produce some of the biggest music festivals in the country, with APE bringing the Outside Lands Music and Arts Festival to Golden Gate Park every summer — plan to help book music acts at Chase Center, and received a request directly from the mayor herself: Beyoncé.

“I have a commitment that eventually she’s going to be here,” Breed said.

Breed joked at the news conference that she had hoped Beyoncé would be the first act to perform at the new venue. But, she added, in the meantime, “We have an incredible local talented artist that will be headlining at the Chase Center. They are just as good as Beyoncé — but don’t tell Beyoncé I said that.”

The Warriors will continue to announce the first round of acts coming to the 18,064-seat venue over the next few days as part of an event they’re dubbing Reveal Week, which culminates in a news conference helmed by Welts and an as-yet-unnamed performer at 4 p.m. Friday.

It will be streamed live online on the venue website and NBC Sports Bay Area.
