For Event 2, Deltron 3030’s second concept album set in a dystopian future, the alt-hip-hop trio of Dan the Automator, Del the Funky Homosapien, and Kid Koala brought together a hodgepodge of featured artists. Actors David Cross, Amber Tamblyn, Joseph Gordon-Levitt, and Mary Elizabeth Winstead (with whom Dan the Automator collaborates as part of jazz-pop duo Got a Girl); musicians including AWOLNATION’s Aaron Bruno, Rage Against the Machine’s Zack de la Rocha, singer/multi-instrumentalist Emily Wells, and rapper Black Rob; and chef David Chang all contribute to the album’s futuristic feel, some through skits, others through vocals. Released 13 years after the trio’s self-titled debut, Event 2 is just as sonically epic as its predecessor. The Showbox, 1426 First Ave., 628-3151, showboxpresents.com. 9 p.m. $29.50 adv./$35. All ages.
