Metallica will team up with the San Francisco Symphony on September 6th to open the new Chase Center in San Francisco. The classical orchestra and Rock and Roll Hall of Famers will be the first acts to perform at the new 18,064-seat arena that will serve as home to the NBA team Golden State Warriors in the fall.

The pairing was announced on Monday (March 18th) at a press 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 and CEO Joe Lacob, Warriors president and chief operating officer Rick Welts and San Francisco mayor London Breed.

Metallica last played with the San Francisco Symphony in 1999, with the performance released as the Grammy-winning live album S&M. Ulrich recalled being more focused than usual for that show: "When you play as many shows as we do, sometimes you have a tendency to sit and look at the lighting rig, and the shows in San Francisco were probably the most focused and the most -- you know, it was really sort of like being part of a team. When you’re four guys, it’s one thing, but when you’re, like, 90 guys or whatever, it’s sort of like a different thing. So everybody really stepped up to the plate."

Speaking about what it is like to perform with an orchestra, Hetfield said at the press conference, "There's more people on stage. And there's actually real musicians on stage. And we're a lot more nervous. But it adds to the power. It adds to the opportunities for dynamics, for creating moods with the music, bringing people in, walls of sound -- all kinds of great opportunities added by having a symphony along with you, along for the ride."

Tickets for the concert go on sale at 10:00 a.m. on Friday (March 22nd) at ChaseCenter.com. Metallica fan club members will be allowed to access them via an exclusive pre-sale at 9:00 a.m. on Tuesday (March 19th).
