Cyclorama, Boston Center for the Arts, 539 Tremont St., 8:00pm. $10.

Music

-- When Piebald says goodbye (again), they really say goodbye (again). The second half of their final show is tonight, and the Everyday Visuals are the openers. Middle East Downstairs, 472 Mass. Ave., Cambridge, 7:00 pm. Sold out. (CR)

-- "What is Change?" a rally hosted by Akrobatik, brings Boston's hip hop, latin, and reggae music communities together with community organizers. It's a voter registration drive that dovetails with an Obama rally across the way. Boston Common, 11:00am-5:00pm. Free.
