According to the Guardian, Fuck Buttons are the 'Kings of Noise', and four other 'noise acts' I should check out are Factory Floor, Deafheaven, Oneohtrix Point Never, and Vatican Shadow.
In the comments, dsmith9 helpfully says, apparently without irony, "I don't think the author really knows what is noise. Try Pan Sonic instead."
dondi on the other hand says that Fuck Buttons are "noisy but not nearly as abrasive as people make out. As are Oneohtrix, Factory Floor and Vatican Shadow. Death Grips on the other hand....Jesus!" Wait until this guy discovers the blistering white noise of Sonic Youth!
ElQuixote though, he gets it: "KINGS OF NOISE? ISN'T THAT LIKE KINGS OF TRASH?"
