The Tune-Up Party will take place alongside several other free downtown activities. About a quarter-mile downstream along the scenic Shiawassee River, the Owosso Farmers Market’s Moonlight Market will run from 5:30 to 8:30 p.m. at Curwood Castle Park, featuring artisan vendors, food, treats, family activities and more.
Nearby, the 2026 Summer Concert Series will feature Midday Sun from 7 to 9 p.m. at the Mitchell Amphitheater. Midday Sun is an indie rock band from Mid-Michigan featuring original music and selections from the 1970s, 1980s, 1990s and 2000s, along with pop favorites. The free Summer Concert Series is presented by the Cook Family Foundation, City of Owosso Parks & Recreation Commission, Owosso Main Street & DDA, and the Lebowsky Center for Performing Arts.
Visitors can also stop at the Shiawassee Arts Center to explore its special Year of the Nonprofit exhibition, on view through August 29. Through photographs, storyboards, memorabilia and personal stories, the exhibition shares the visual histories of 11 Shiawassee County nonprofit organizations, including the Shiawassee Regional Chamber of Commerce. The exhibit celebrates the organizations, volunteers and community members whose service helps make Shiawassee County a better place to live, work and thrive. The Year of the Nonprofit campaign and exhibition are sponsored by the Cook Family Foundation.
Together, the events will create a connected evening of classic cars, local shopping, food, vendors, community history, family activities and live music throughout Downtown Owosso.
Vehicle registration is not required to participate in the Tune-Up Party, but registration is required to be eligible for the collector T-shirt and prize drawings. Vehicle parking will be available on a first-come, first-served basis and is not guaranteed through registration.
Participants can register here.
A digital map showing the Back to the Bricks event footprint, participating businesses and attractions, and a walking route connecting the evening’s activities is available here.
Visitors should expect temporary street closures and traffic changes south of Main Street during the event. Additional parking, traffic and event information will be released through the Shiawassee Regional Chamber of Commerce, Downtown Owosso and Owosso Farmers Market social media pages before July 30.
