Marching back into their old stomping grounds, the Petaluma Music Festival is bringing their popular Fat Tuesday Mardi Gras Party fundraiser back to Lagunitas. And it wouldn’t be a Mardi Gras party without the King Street Giants kicking it off at 5:30pm, bringing their own special version of New Orleans music to the Bay Area and beyond. Whether they’re playing in clubs or on the streets, The King Street Giants are infamous for radiating an infectious energy and always having a blast!

Come hungry and enjoy Bayou on the Bay (Cajun/Southern fusion) and Galvan’s Mexican Food (Best of Sonoma County Winner 2024) food trucks. And of course, the taproom is open with all the Lagunitas faves plus some new releases – only available at the brewery.

This year marks the 18th annual Petaluma Music Festival which raises funds for Petaluma Schools music programs. To date the local non-profit has donated over $475,000 to help keep music in the schools. 2025 line-up will be announced March 1st. The festival takes place at Sonoma-Marin Fairgrounds in Petaluma on Saturday, July 26, 2025.
