Also playing acoustic sets will be  (Alice in Chains),  (), Pat Monahan (Train), Linda Perry and Joe Satriani. There will be solo songs, duets, jam sessions and special guests.

The event benefits the Pediatric Cancer Program at UCSF Benioff Children's Hospital. "Acoustic-4-A-Cure" was created by Hagar and Hetfield, whose vision was to raise funds and awareness for the Pediatric Cancer Program at UCSF by bringing together some of their friends and throwing a must-see concert for fans.

Last year's inaugural concert included numerous memorable moments such as Hetfield's acoustic rendition of The Beatles "In My Life," Green Day's Billie Joe Armstrong, Hetfield and Satriani playing a medley of Bob Seger's "Turn the Page" and "Boulevard of Broken Dreams," and the closing all-star jam with Hagar, Hetfield, Armstrong, Satriani, Monahan and Nancy Wilson performed Bob Dylan's "Rainy Day Women #12 & 35" to close the show.

Tickets for "Acoustic-4-a-Cure" go on sale Friday, April 10 at this location.
