Nathan Reusch and Mike Russo co-own a local label called the Record Machine, so it's safe to assume they boast decent vinyl collections. But they won't actually spin wax during Switched On, the first in a proposed series of dance parties organized by Reusch and Queens Club singer Daniel Eaton. They'll let Record Machine artist Max Justus make his own case live. Justus, whose Record Machine debut, Five Leaping Leopards, arrives this summer, composes electronic instrumentals that range from space-age funk to staticky industrial blasts to warped hip-hop loops. His backbeats remain steady, meaning the stylistic shifts won't disturb the dancers' grooves. Kansas City trio Queens Club blends dance-punk rhythms with adult-alternative hooks: Its single "Danger Kids" sounds like Dave Grohl fronting Bloc Party.
