I've thought of another one. A rap group can do Gregorian chant.

I find it fun to think of these combinations - it requires one to consider the inner nature of a kind of music, then conjure up its opposite.

Wordsworth called this "unity in multeity."

I did wear my hearing protectors all evening. I saw another woman who was sitting with her family and had her fingers in her ears. I gave her a hearing protector from my box. She was pleased.

I like the Mack brand of hearing protectors, little blobs which look like (but are not) paraffin.

Not to get too contentious about this, there really are people who find it physically painful when two trumpets, not perfectly in tune, let 'er rip into a couple of amplifers 7 feet high. I asked my nephew if that didn't bother him, and he said, "No, I've gone to too many rock concerts."
