a hellish atmosphere

A Vatican composer is to stage an opera based on Dante's Divine Comedy, with visions of heaven, hell and purgatory.

"Reports suggest heaven will be full of classical style melodies, the limbo of purgatory will be illustrated with Gregorian Chant, with hell full of more jarring music.
Frisina said the use of rock music to describe the devil's den was not a value judgment on the genre but that rock's 'violent and rebellious tones' help create 'a hellish atmosphere'."

Amazing !

Try and suggest that perhaps there can be a value judgment made on rock and every one is up in arms saying you can't decry rock. But it is "violent and rebellious" in its tones.

That is what I have been saying since it was created ! That is why I do not like it or listen to it !
