Sammy Hagar and James Hetfield Announce 2015 Acoustic Benefit Show

Sammy Hagar and James Hetfield have announced their second Acoustic-4-A-Cure benefit show, which will take place on May 15 in San Francisco.

Last year's inaugural outing of the one-night, sold-out concert -- which included Hagar's Chickenfoot bandmate Joe Satriani, Green Day's Billy Joe Armstrong and Nancy Wilson of Heart -- included stripped-down versions of rock classics like the Beatles' "In My Life" (performed by Hetfield) and Bob Seger's "Turn the Page" (by Hetfield, Satriani and Armstrong).

On tap for this year's show are Satriani, Alice in Chains' Jerry Cantrell, Train's Pat Monahan, singer-songwriter Linda Perry and Red Hot Chili Peppers drummer Chad Smith. Others are expected to join the lineup over the next few weeks.

"Each legendary artist will be performing acoustic sets -- with once-in-a-lifetime musical moments, duets, jams and surprise guests planned," promises a press release announcing this year's show." Acoustic-4-A-Cure will fund children's brain-tumor research at the Pediatric Cancer Program at UCSF Benioff Children's Hospital. Tickets for the concert -- which will take place at the Masonic in San Francisco -- go on sale Friday at 10AM.
