Seattle's fourth annual Decibel Festival offers four days of world-class electronic music at various venues, but tonight's Death of the Party showcase is a definite highlight, featuring Diplo's polyglot party jams, Switch's twitchy house, Simian Mobile Disco's raucous electro, and the DJ skills of Seattle's Fourcolorzack and Pretty Titty. It's going to be a hell of a party, but it's also going to be an ecstatic and exhausting weekend, so try to pace yourself. (Neumo's, 925 E Pike St, 8 pm, $15 adv/$17 DOS, 21+.)
