The ever evolving Grimace Federation are headlining Kung Fu Necktie tonight. Generally, they’re known for experimental post rock the likes of Tortoise, but with Wes Schwartz’s and Chris Woods’ growing interest in metal shows, expect a darker, harder-edged sound as they get set to release a new album this fall/winter. I would definitely consider this band one of the many highlights of the Philly music scene that tends to push the boundaries of the “Philly sound” and create something exciting and new. Kung Fu Necktie, 1250 N. Front St., 8pm, 21+ – Adam G.
