Fantastic, especially the young girl doing rage against the machine, when there is a break in the drumming and you see her working herself up to come in again. Had me grinning from ear to ear, so enthusiastic. At that age I struggled using a fork never mind mastering the drums.
Slayer are definitely the loudest band I've ever seen live. Supported by Machine Head in Wolverhampton back in the early 90's. It was a while before the ringing in the ears dissipated after that one
Napalm Death in a basement bar with the roof about 3 metres high comes second for exactly the same reason you've givenI saw machine head supporting Rammstein and always remember the guitarist running off the stage and then running back on. Naked. Bizarre.
Loudest for me was either The Ramones or Saxon. Not because they were loud but because they were in terms of the size of the venues. I have never seen people enjoying the music from the toilets. They should have had a health warning
