The Washington, DC band Mikau has a truly insane take on a much-maligned style. In a lot of ways, Mikau’s music is routed in the mall-metalcore of the ’00s — the whiny clean-singing choruses, the gut-rumble guitar crunch, the screamy breakdowns. But Mikau, whose drummer Austin O’Rourke is also in Infant Island, put that sound into a blender, turning it into chaotic basement music. It makes for intense, unsettling fun.
