The 8th annual Honk! Fest of Street Bands returns to Boston, Somerville, and Cambridge this weekend. The festival kicks off on Thursday night in Union Square with pre-Honk! musical performances and continues into the weekend with lantern making workshops, parades, and street bands. According to the website, “honkers” are street bands drawing influences from New Orleans brass bands to traditional Balkan folk music. This festival brings them together for a fun, free event. Honk! Fest’s entire schedule can be found here.
