Popular Science, the experimental music series organized by Grimace Federation and Brooklyn dubstep maestro Sonkin, comes to an end tonight at Kung Fu Necktie. And it ends in a loud way as the local electronic trio is joined by metal psychpaths A Life Once Lost. The band has been grinding away since 1999, and returned last year with their latest full-length album Ecstatic Trance. So expect a rager, especially since Grimace Federation could be previewing some new tracks from their most recent recording session. Add in the industrial doom of Author & Punisher and the electronic cello of Helen Money, and you have an eclectic evening of music that is sure to expand your musical taste. Kung Fu Necktie, 1250 N. Front St., 8pm, $5, 21+ – Bill McThrill
