You Say Party! We Say Die! to play at Echoplex on Saturday

The Canadian post-punks in You Say Party! We Say Die! Thoroughly live up to the name with serrated dance jams equally likely to inspire you to make out with your neighbor or punch him or her in the sternum. New album “XXXX” elaborates on the early-aughts disco formula with a real sense of arena-ready yearning. Echoplex, 1154 Glendale Blvd., L.A. 8:30 p.m. Sat. $14. www.attheecho.com.
