Sammy Hagar

Sammy Hagar and Metallica’s James Hetfield have organized a star-studded benefit concert slated for late spring.

Titled Acoustic-4-A-Cure, the inaugural event will take place May 15 at the Fillmore in San Francisco, and will feature appearances by Billie Joe Armstrong, Joe Satriani, and Heart’s Nancy Wilson, among others.

Jam sessions, surprise appearances, and once-in-a-lifetime duets are promised. Proceeds from the event—which will consist of all-acoustic sets—will go to the Pediatric Cancer Program at the Bay Area’s UCSF Benioff Children's Hospital.

“I've seen firsthand the great work they're doing and how vital community support is,” said Hagar, in a prepared statement. “I ran the idea of a benefit concert by James, and we quickly had an amazing lineup of artists on board.”

Tickets go on sale this Friday (March 21).
