"Every two bars I'm feeling something."
That's Chuck Sher, talking about playing upright bass on a folding stage in Putnam Plaza, not about a concert hall. He says it most Sundays, because most Sundays he's there, between the Speakeasy restaurant and Petaluma Pie Company, running Jazz in the Plaza with whoever's free that week from the Bay Area's session-musician circuit. If you've walked through downtown on a Sunday afternoon this summer, you've probably heard him before you saw him.
Here's the part that's easy to miss if you just enjoy the music and move on: Jazz in the Plaza wasn't built as a permanent institution. Neither was the other free weekend ritual that now anchors Petaluma summers, the floating concert down at the river. Both started as pandemic improvisations, ways to keep musicians paid and the town from going quiet during 2020 and 2021. Neither one folded when things reopened. Both are still running in August 2026, and between them they've become the actual scaffolding of how this town spends a summer weekend.
Two lockdown reflexes that never turned back off
Jazz in the Plaza is produced by Music in Place, a nonprofit founded in the early pandemic by Sonoma County residents Rodman Marymor and David Poe alongside San Jose State University music professor Dr. Aaron Lington. The original idea was closer to triage than tradition: keep working musicians on stage and paid while every indoor venue in the county was shut. The organization now also runs a Sunday series at Sonoma Plaza's Grinstead Amphitheater, but Petaluma's Putnam Plaza show is the one that's run continuously and become the more recognizable of the two.
Down at the water, the same instinct produced Bands on the Basin. It was dreamed up in the summer of 2021 by music lover and event producer Scott Ferrara as a way to get people back outside, and it's grown from a creative COVID-era stopgap into an annual fixture that funds its own existence. This year's edition ran July 11 at the Turning Basin, with Sebastian Saint James, SoulShake, and Foxes in the Henhouse playing to a crowd that was mostly floating.
Neither series ever got a corporate sponsor or a city marketing push. They're both still run by the people who started them, still free or close to it, and still the reason a Petaluma weekend feels different from a weekend spent driving to a winery.
The Sunday that runs itself
Jazz in the Plaza happens every Sunday from 1 to 3:30 p.m., April through November, weather permitting, at Putnam Plaza on the walkway connecting Kentucky Street and Petaluma Boulevard. The lineup rotates constantly. Sher anchors most weeks on bass, but the rest of the quartet changes: guitarist Randy Vincent, pianist Ken Cook, saxophonist Rob Sudduth, and drummer David Rokeach have all cycled through, along with a long list of other Bay Area players. Some weeks it leans traditional swing, other weeks it drifts into something closer to soul.
What makes it stick isn't just the music. It's the location. Wedged between two food businesses on a pedestrian cut-through, it catches people who never planned to attend a jazz show. Families push strollers through. Kids sit at the edge of the crowd. It's donation-based, not ticketed, which means nobody has to decide in advance whether tonight is a jazz night. You just have to be walking through downtown at 1 p.m. on a Sunday.
The river that finally pays rent
For most of Petaluma's recent history, the river has been scenery. Something you glance at from the Riverfront Café patio or cross on the D Street Bridge. That's shifted. The Floathouse Petaluma operates out of the Turning Basin, launching kayaks, paddleboards, and pedal-powered Hobie boats from Cavanagh Landing off Weller Street every weekend from 9 a.m. to 5 p.m. The river now functions as an actual amenity rather than a backdrop, and Bands on the Basin is the clearest proof of that shift: a concert you attend by boat, in a downtown that didn't have a real reason to get on the water five years ago.
The mechanics of the event underline the point. Boat rentals during Bands on the Basin run in tight two-hour blocks because demand outstrips the fleet, and the racks are reportedly empty of boats well before showtime most years. That's a strange problem for a town to have about its own river, and it's a new one.
What fills the rest of the week
Jazz and the river cover Sunday. The other five days have their own smaller, equally specific rituals, most of them clustered around live music that never leaves downtown:
- Friday evenings, the Buckeye Boys play bluegrass at Aqus Café on H Street, while a few blocks away the Blues Defenders take the outdoor waterside deck at Riverfront Café, where seating is first-come and the crowd spills onto the boardwalk overlooking the water.
- Saturday nights, The Big Easy on American Alley hosts rotating acts with no cover, including a recent rockabilly set from The Rocket Wheels covering Gene Vincent and The Stray Cats, with a full bar and menu from The Speakeasy next door.
- Sunday afternoons, before or after the jazz series wraps, Griffo Distillery opens its roll-up doors for an afternoon of live music with food from Bodega Market Deli.
- Once or twice a month, Brooks Note Winery in the stretch of North Petaluma Boulevard that locals have started calling the NoBo district hosts a wine-fueled version of Bingo built around song titles instead of numbers.
None of this is coordinated by a single calendar or a city department. It's a patchwork of small businesses that have each independently landed on the same conclusion: a weeknight or weekend slot with live music and no cover charge is worth more to a Petaluma bar or café than the same slot without one.
New rooms opening around the ritual
The businesses filling in around this rhythm are worth naming, because they're following the pattern rather than creating it. Chef Christian Caiazzo and Katrina Fried, who've already built two Italian concepts in downtown Petaluma under the Stellina name, are opening a third: a bakery and café at Lakeville Square, in a storefront that's cycled through Noah's Bagels, Bright Bear Bakery, and Tea Rex Boba over the years.
Meanwhile the long-vacant IHOP building on Old Redwood Highway, empty since the end of 2024 with nothing but a For Lease sign in the window, has a beer and wine license application posted for a new restaurant called Blue Plate. It's unrelated to the San Francisco restaurant of the same name, according to that restaurant's own owner, who said he'd never heard of the Petaluma project before a reporter called him.
Both openings say something about confidence in downtown Petaluma as a place people actually spend evenings, not just a place they pass through on the way to somewhere with more going on.
What's left of the season
Jazz in the Plaza runs through November, weather permitting, which means there's still a real stretch of Sundays left as of mid-August. The Floathouse keeps its weekend hours through the fall, and the Friday and Saturday circuit at Aqus Café, Riverfront Café, and The Big Easy shows no sign of slowing before the weather forces it.
The bigger point is one most people who live here haven't quite put together: two of Petaluma's defining free rituals exist because a handful of specific people refused to let a pandemic shutdown be the end of live music in this town. Chuck Sher didn't set out to build a Petaluma institution. Scott Ferrara didn't either. They built stopgaps, and five years later the stopgaps are what a summer weekend here actually looks like.
If you're already home in Petaluma, none of this requires planning much beyond showing up. If you're the kind of person who reads a piece like this because you're weighing whether a town like Petaluma fits the life you want, that's a different question, and it's one Lauren Berg and the team at Berg Group spend their days helping people answer with real neighborhood knowledge rather than a listing sheet. Reach out and request a tour when you're ready to see what a Petaluma address actually feels like on a Sunday afternoon.
