With January already behind us, everyone is looking forward to February’s most popular holiday—Mardi Gras! In the spirit of the extravagant event, the town of Petaluma is once again taking Fat Tuesday to the streets with the 25th annual Mardi Gras Mambofest. This year, the all–New Orleans R&B revue act Rhythmtown Jive once again leads the lively parade from Putnam Plaza through downtown Petaluma, and back up American Alley, before the festivities move indoors for a dance party in the coolest underground jazz club in the county. The Mambofest kicks off on Tuesday, Feb. 9, at the Big Easy, 128 American Alley, Petaluma. 5:30pm. $5–$7. 707.776.4631.
