Ever since Metallica were announced as the headliners for the Saturday night at Glastonbury, June 28, there has been a backlash from fans and disparaging comments from bands such as Mogwai, Arctic Monkeys and Bombay Bicycle Club.

But Ulrich says that the negative reaction has no impact on his band. Following Friday's widely-viewed video interview, the drummer has talked to us in more depth about the reaction. "To be totally honest," he says, "I don't know how serious I can take all of it. I don't sit glued to the iPad following whoever is the next person who has an opinion about Metallica. I know that almost on a daily basis there is some musician somewhere who gets asked what he thinks about Glastonbury and Metallica, and I find the good in that - that after more than thirty years, we can still get talked about. I guess it's fun that you can still make some waves, without doing anything other than saying yes to an invitation to a festival. So, happy days!"
