Grimace Federation creates interwoven instrumentals that could stand well on their own, but together create a symbiotic chaos. Each note is pushed to the aural foreground, bombarding the ears so that the same song sounds different upon its second rotation. When space exploration finally results in alien contact, I would imagine our intergalactic brethren playing music similar to Grimace Federation’s: vast and echoing, much like the expanse of space, music that, with all its complexity, does not require words to stir emotion. And plenty of it will be poured out this evening at Kung Fu Necktie. (We are sad to hear about the sudden passing of Grimace frontman Wes Schwartz’s father, which just happened two days ago. Our thoughts and best wishes go out to him and his family.) Kung Fu Necktie, 1250 N. Front St., 9pm, $10, 21+ -Shaylin O’Connell
