I'm laughing at Goths being the world's worst generic gatekeepers. They certainly can be. I ended up leaving the old Facebook group 'I love 80s Goth' because I wanted to participate in shared love of music and nostalgia, not witness a load of arguments!
Still love all my old goth bands.
As for heavy rock, QOTSA were another one I've lost count of the number of times I've seen at festivals. They put on some great sets, but with Era Vulgaris they/he (QOTSA is really only Homme) went off the boil and after that seemed to peter out.
One of my most-played albums is Deathstars' 'The Perfect Cult'. Great, great album. Their latest 2023 offering 'Everything Destroys You' is also growing on me.
I have to share a memory of Korn's set at Download, think it was around 2009. They covered Floyd's 'The Wall' (most Floyd covers are sacrilege, said as a die-hard fan of them too) but that performance was electric. When the song finished there was a beat of silence that seemed to last several seconds, and in which you could have heard a pin drop in that arena. After that the most enormous roar went up from the audience that probably could have been heard for miles. What an amazing band, and Jonathan Davis is fantastic.
Pendulum, the drum and bass band, started out to a lukewarm reception, with a lot of uparse comments asking WTF they were doing at a rock festival. Then those who had buggered off into disgust to the second stage gradually came drifting back. Within 15 minutes they had that whole field rocking - came back a few years later if I recall correctly to an ecstatic reception. Totally unexpected, they won a new fan in me that day.
BRMC and NiN I also love, although BRMC are more bluesy. They are great, though!
