I looked at that picture 4 times throughout the day and just now remembered that my friend dragged me to Mayhem fest like 10 years ago. It was pretty funny. Unless it was another metal fest, IDK. I just remember a bunch of identical, generic metal core bands where the lead singer always puts one foot on the amp, unironically, to growl, and then the band all sleepily perform the same breakdown every song.
And then 80 year old anthrax is killing it on the other stage
