Erase Errata scavenge the ruins of riot grrrl and disco punk to bring us dark, nervously energetic rock that sounds both paranoid and passionate. The trio jams coercive rhythms, twitchy guitar, and the odd blast of trumpet into quick, careening tracks that are just a second shy of exhausting. Adult. make clean, icy electro and skuzzy, gothic no wave, bound together by the disaffected vocals of Nicola Kuperus. The recorded output of Adult. may not be what it was, but their live shows, like Erase Errata's, are still totally magnetic and unsettling. (Chop Suey, 1325 E Madison St, 324-8000. 9 pm, $10, 21+.)
