Before withdrawing into winter hibernation, hardcore-metal trio Fight Amp headlines tonight at Kung Fu Necktie. With a road-tested heavy artillery sound that is equal parts brute-strength/raw-fury calculated into a caustic sludge, Fight Amp materializes itself into a thick oozing heavy concoction engulfing listeners. Set off by undeterred in-your-face instrumentation that seems to build and simultaneously feed/morph off its individual components (guitar/bass/drums) – each capable of leading the charge at any moment. This potent combination of controlled speed, power and will unite as a force. The bill also includes fellow Brutal Panda Records noise rockers Ladder Devils as well as punk rockers Braille. Kung Fu Necktie 1250 N. Front St., 9:30pm, $8, 21+ – Michael Colavita
