Legendary metal act Metallica have revealed that they will work with legendary producer Rick Rubin on the followup to their 2008 album Death Magnetic.
Bassist Robert Trujillo told 93.7 KCLB Rocks! radio: "Yeah. I love working with Rick. Rick, to me, he's sort of a Zen guru spirit that Metallica needs right now.
"Not to say that we need it, because we're getting along incredibly well, we're really excited to write some new music.
"There's no shortage of riffage in Metallica world right now. And I think it's only gonna get better."
Metallica will play The Big 4 concerts with Slayer, Megadeth and Anthrax around the world before entering the studio.
