The ninth annual HONK! Festival, featuring homegrown music and activist bands, will take place October 10 throughout the neighborhoods of Somerville, Cambridge and Boston. This lively event is free and open to everyone, rain or shine.

Founded in 2006 in Davis Square by members of the Somerville-based Second Line Social Aid and Pleasure Society Brass Band, HONK! is a rousing sociopolitical music spectacle showcasing social activist street bands from around the world. Musicians from more than two dozen bands will come together to share their approaches to merry making while also instigating positive change in their communities.

HONK! 2014 will also feature a “Day of Action” on Friday, October 10 to set the stage for a targeted weekend-long partnership between activist bands and local socio-political organizations. For more information on this initiative, visit HONKfest.org/2014-festival/friday-day-of-action-2014/.

Cost: Free. To learn more and see the 2014 HONK! schedule, visit HONKfest.org. Updates can also be heard by calling 617-383-HONK (4665).
