“Honk!” in Boston and Providence

“Honk!,” the third-annual giant festival of international activist marching band awesomeness, returns to Boston (well, actually Somerville and Cambridge) today and tomorrow. The don’t-miss-it main event is Sunday's “Parade to Reclaim the Streets for Horns, Bikes and Feet,” which features 24 brass bands and various community organizations marching and making beautiful music together from Davis Square to Harvard Square beginning at noon. Among the many bands performing is Providence’s What Cheer? Brigade, pictured above at last year’s parade. (More photos from last year are here.)

The festival moves to Providence with “Brass Bands Conquer the New World” beginning at 5 p.m. Monday in Kennedy Plaza and then marching down Washington Street to AS220 on Empire Street (where admission is $10).
