Now in its 21st year, the HONK! Festival brings 35 U.S. brass and street bands to the Somerville and Cambridge area for three days of free, unplugged, politically charged music. Running October 9 through 11, 2026, the festival kicks off in Davis Square and the surrounding Somerville neighborhoods on Friday and Saturday, before a massive Sunday parade rolls down to Harvard Square — where it arrives in time for the square’s 47th annual Oktoberfest.
This year’s lineup spans the country: from the Rude Mechanical Orchestra (New York) and Brass Liberation Orchestra (San Francisco) to the Detroit Party Marching Band and Yes Ma’am Brass Band out of Austin. Local bands — including the founding Good Trouble Brass Band, School of HONK, and several other Somerville-based outfits — anchor the home turf. Six international bands from Brazil, Chile, Italy, England, Germany, and Canada will join via live video stream.
Beyond the performances, festivalgoers can participate directly. The pick-up ensemble Band Together welcomes players of any level, while ArtHONK! and Singing Resistance offer additional ways to join in rather than just watch from the sidewalk.
HONK! started in 2006 with just 12 bands — three local, eight from around the U.S., and one from Vancouver. That original model, rooted in the idea that mobile brass bands can respond to what’s “very wrong in their neighborhoods” by hitting the streets loudly and collectively, has since spawned more than 20 independent HONK! festivals worldwide. The Somerville festival remains coordinated by the Good Trouble Brass Band, the same group that founded it two decades ago.
The full 35-band roster and schedule details — still being finalized — are available at honkfest.org. Anyone interested in volunteering can reach out to volunteer@honkfest.org; those able to host visiting musicians should contact housing@honkfest.org. The festival receives support from the City of Somerville, the Somerville Arts Council, and the Harvard Square Business Association.
All events are free and open to the public, rain or shine.
