Last night (May 12), the 10th Annual MusiCares MAP Fund benefit concert was held at Club Nokia in Los Angeles. Black Sabbath legend Ozzy Osbourne and Village Studios owner / CEO Jeff Greenberg were the night's honorees, but Metallica were also an important part of the show, performing a four-song set of classic covers.

During the MusiCares benefit, Ozzy was given the Stevie Ray Vaughn Award for the Sabbath singer's commitment to help individuals who struggle with addiction. “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,” says Osbourne. “This organization literally saves lives.”

Metallica were later added to the event's bill, which already included Ozzy's solo band featuring Slash as a guest guitarist. "It’s no secret that Ozzy has been a major presence throughout our entire lives," stated Metallica, "and we are so humbled and honored to be with Ozzy for this special evening.”

Metallica's four-song acoustic set began with Rare Earth's 'I Just Want to Celebrate' before the thrash legends dove into 'When a Blind Man Cries' by Deep Purple. Rounding off the performance, Metallica concluded by covering the Beatles' 'In My Life' and Ozzy Osbourne's 'Diary of a Madman.'
