Personally I think the best rating you can get for a loud ass rock show is a noise complaint! Metallica crushed their 16-song set at the Download Festival last night at Donington Park with noise complaints coming in from 15 miles away!
I'd say Metallica's M72 World Tour is off to a bad ass start. They only play weekend shows but set up for two nights in each city. This past weekend was in Hamburg, Germany and fans had the chance to experience a super deep dive into their Black Album. They don't play that song very often,
