So Heavy

It’s dangerous to become too absorbed in Blowupnihilist‘s music. Those captivatingly eerie, ambient waves yield to harsh, grinding metal. It’s like getting lulled into a daydream by the repetitive clamor on an assembly line, only to be jolted by the abrupt, bloody realization that your hand has become lodged in the machinery. The Vancouver, Washington, instrumental act combines industrial rhythms, crackling feedback, violent screams and wind-tunnel distortion, recalling the most chaotic bits from Nine Inch Nails’ “Wish” without any hint of that group’s more melodic material. Also hailing from Vancouver, the duo Abominable Iron Sloth converts heavy, droning sludge into massive grooves, then shouts over the riffs. Local DJ FIRE4EFKT supplies bottomless bass drops, intense pulsing keys and robotic voices. The noise begins at 8 tonight at the Foundation Room (1221 Union, 816-283-8990). Tickets cost $5.
