Philly’s Birth Noise might have come into the world kicking, but it certainly didn’t do any screaming. In fact, the young band has yet to even utter its first word. But don’t hold your breath: the noisy trio—reportedly featuring former members of Mass Movement of the Moth, Ingrid, Sick Weapons and Des Ark—deals in dense instrumentals. Birth Noise has also yet to make a peep on the Internet, with one YouTube clip and a few mentions of previous shows the only proof of the band’s existence. Three-bass-guitars-plus-drums quartet Acid Kicks, meanwhile, has a slightly higher profile, including a handful of photos and a trio of barely audible songs available on the band’s Facebook and MySpace pages. Perhaps both bands’ relative anonymity is why tonight’s show at Kung Fu Necktie is free of charge? But the city of Philadelphia loves some noise-rock, and you can probably expect to see both bands’ name in headlines sometime next year—which is all the more reason to see them tonight. Birth Noise performs with Acid Kicks, DJ Jane Pain, and DJ Laura Lawless at 9 p.m. at Kung Fu Necktie; tickets to the 21+ show are free.
