After drawing a record 51,500 fans to Parc Jean-Drapeau in 2025, Montreal’s premier country music festival is doubling down with a headlining duo that bridges the genre’s contemporary mainstream and its folk-rock borderlands. Mumford & Sons and Thomas Rhett will top the bill at Lasso Montreal 2026, the festival announced Monday, with Jon Pardi and Old Dominion rounding out the initial wave of confirmed acts.
The booking marks the first Lasso appearance for Mumford & Sons, Thomas Rhett, and Pardi, three artists whose stadium-filling credentials should help the festival build on last year’s momentum. Old Dominion, meanwhile, return after playing the festival’s inaugural edition in 2022. Rhett and Pardi will anchor Saturday, August 15, while Mumford & Sons and Old Dominion close out Sunday, August 16. That Sunday slot represents a shift for Lasso, which has traditionally staged its second day on Fridays but will now run Saturday-Sunday in 2026.
The festival has also confirmed an indoor Lasso in the City event for Friday, August 14, though details remain under wraps. The full lineup will be unveiled sometime in the new year, with day tickets expected to follow shortly after.
Two-day general admission passes go on sale December 12 at 10:00 AM, starting at $250 CAD. VIP options range from the $385 Festive Terrace pass to the $850 Diamond Ticket, with Birkenstock-sponsored Gold and Sky Saloon tiers in between at $475 and $625 respectively.
For Montreal’s country scene, the announcement lands at a curious moment. Mumford & Sons, once indie darlings who redefined folk-pop in the early 2010s, have spent the past decade navigating lineup changes and stylistic pivots. Their inclusion suggests Lasso is casting a wider net beyond Nashville’s core, something the city’s genre-fluid audiences tend to reward. Rhett, by contrast, is pure Music Row polish, a reliable hitmaker whose crossover appeal has made him a festival staple. Together, they signal a lineup that’s less about purity than reach, which, for a fifth-year festival still finding its footing, might be exactly the right play.
