Yeah, gay shit. Over pretentious hipster crap. And this is coming from a fan of industrial / dark ambient / electronica etc whatever influences them, but they just gay up the whole sound.
And yeah, "witch-house" is pretty terrible in general.
Salem and the whole witch-house crap are really just the dumming down and simplfying of a lof of more obscure genres so hipsters get it.
Death Grips are fuckin dope though
