Dave Grohl, aka the coolest man in rock, is working on a new documentary about Sound City Studios, the legendary LA studio that was home to many classic albums. He recently released a teaser clip, which you can watch above of Metallica drummer Lars Ulrich talking about some of his earliest musical memories. More video clips from the doc can be found on it's official Youtube page.
