We’re over halfway through this year’s Kwanzaa schedule but if you haven’t had a chance to catch one yet, tonight’s principle is NIA at Blue Hill Boys and Girls Club (15 Talbot Ave., Dorchester). Tomorrow, New Year’s Eve, is KUUMBA at the Reggie Lewis Center (1350 Tremont St., Roxbury). New Year’s Day is IMANI at the Museum of the National Center for African American Artists (300 Walnut Ave., Roxbury). All events start at 7pm except for New Year’s Day at 4pm. Support the vendors!
