Guitar great Slash will join Ozzy Osbourne on-stage for a performance at this year’s 10th anniversary MusiCares MAP Fund benefit concert.

Slated for May 12 at Club Nokia in Los Angeles, the event will honor Osbourne for his support of the organization, which seeks to assist musicians who are struggling against addiction. The Black Sabbath frontman will be presented with the Stevie Ray Vaughan Award in recognition of his efforts to support the cause. “I know firsthand about the ravages of addiction and I also know that the MusiCares MAP Fund is a vital safety net for people in the music industry who need help with substance abuse,” said Osbourne, in a prepared statement.

“This organization literally saves lives.” Jeff Greenberg, CEO of The Village studios in L.A., will be honored as well, with a “From The Heart” award. “This annual benefit provides a meaningful way to recognize artists and industry professionals who are on the front lines in the battle to fight this crippling disease,” said MusiCares president Neil Portnow. “It's an honor to celebrate Ozzy and Jeff in our 10th anniversary year, and we know it will be an extraordinary evening filled with heartfelt words and serious rock and roll.”
