WATCH: Metallica Goes Acoustic For Charity Gig

James Hetfield's annual fundraising concert, Acoustic-4-A-Cure, took place in San Francisco over the weekend. The event aims to raise money for cancer research for children.
First started in 2014 and co founded by Hetfield and fellow rock God Sammy Hagar, the event took place in San Francisco's Fillmore venue. During the show Hetfield took to the stage to perform an acoustic version of Metallica's 'Motorbreath'. Also performing at the show was Joe Satriani, Tommy Lee and his daughter Cali.
As well as 'Motorbreath' Hetfield also performed 'The Unforgiven' and 'I Put A Spell On You' by Screamin' Jay Hawkins. Metallica are progressing with their tenth studio recording which is expected at some point later this year. In March drummer Lars Ulrich told Rolling Stone, "I think it will be a pretty in-your-face year, at least the back half of it". Ulrich also said the band are getting ready to finish the new record and to play some tour dates behind it.
