Anne of Green Gables never saw this coming! The fourth edition of Sommo Festival, scheduled for September 11-12, 2026, has just announced pop-rock duo Twenty One Pilots and singer-songwriter sombr as headliners.
Born in 2023, the inaugural Sommo Festival (pronounced like FOMO, per the festival’s Instagram) staged a genre-spanning celebration of live music and culinary talent on the shores of Cavendish, Prince Edward Island. For country fans, it’s a familiar town — the coastal community also hosts Cavendish Beach Music Festival, an outdoor concert packed with genre titans like Luke Bryan, Zac Brown Band, and Shania Twain.




Not to be outdone, Sommo has racked up an impressive resume. In just three years, the two-day affair has drawn names like Maggie Rogers, Noah Kahan, Charlotte Cardin, and Alanis Morissette. Designed for foodies and fans alike, Sommo Festival complements live performances with a slew of “culinary experiences.” Previous culinary lineups have featured Gail Simmons, Amanda Freitag, Old Time Hawkey, and Mary Berg, to name a few. For its fourth iteration, Sommo is set to deliver a sizzling summer lineup.
“2026 is moving to an entirely new level,” says Ben Murphy, CEO of Whitecap Entertainment. “Landing Twenty One Pilots and sombr is a massive moment for us.” More announcements will follow, Sommo organizers say, but for now, we know that Twenty One Pilots will kick off the festival on September 11th. Expect to hear songs from 2025’s Breach alongside a smattering of past hits. Meanwhile, sombr — fresh off his debut album, I Barely Know Her — will take the stage on September 12th.



“We can’t wait for fans to experience the energy they’re going to bring to the main stage,” Murphy continues. “Between the world-class music, our expanded culinary offerings and the atmosphere that only Sommo can deliver, this is shaping up to be our most unforgettable year yet.”
Tickets are on sale now, starting at $179 for a single-day pass or $275 for all-weekend access. True superfans will find a plethora of upgrades, from sunroof seating to VIP tables and hotel packages.
