A fantastic example of a man / band that is embracing the silliness is Rainbowdragoneyes. He mixes death metal with chiptune and trash pop voice modulators but still produces very intricate and well designed albums, that tell engaging stories, like this one: https://rainbowdragoneyes.bandcamp.com/album/the-secret-mirr...
He'd fit in well at the Bangface Weekender I go to religiously, they've had both plenty of chiptunes artists and Napalm Death play there in the past :) https://www.bangface.com/
