Even dream of joining a vocal ensemble? Participate in Songs and Sounds with/for Cars, a vocal ensemble that accompanies the sound of passing traffic. Detroit-based artist Nick Tobier, whose work deals with the social lives of public places, and Chicago artist Regin Igloria, who runs the community arts organization North Branch Projects in Albany Park, will train participants on the spot!
