John Naughton has a less than flattering opinion of them based on their activities rather than their performance:-
I’ve never knowingly listened to anything by Metallica, but I remember well how aggressive they were in the Napster era. They’re old-style control freaks.It struck me that Metallica is an anagram of cameltail. Equally, as I have never seen the buggers sing, dance or entertain - I can't for the life of me remember if camels have tails! Crosswords do some funny things to your brain.
