Metallica bassist Robert Trujillo admitted in a new interview with Classic Rock that work on the band's next album -- its first official release since 2008's Death Magnetic -- has been sidetracked in recent months by touring and by preparing the feature film Metallica Through The Never for release. Trujillo told the magazine, "Before all the film stuff, we were jamming these ideas and having a lot of fun. But we got sidetracked. In 2014 it'll be all about getting new music -- without any interruptions, hopefully." Metallica Through The Never is out in IMAX 3D theaters on September 27th, with the film expanding around the country on October 4th.
