Sommo Festival has revealed its massive 2026 headliners, with Twenty One Pilots and Sombr set to top the bill for the two-day celebration in Cavendish, Prince Edward Island. The fourth edition of the fast-growing music and culinary festival will take place on 11th and 12th September, 2026, marking another major milestone for Whitecap Entertainment.

Twenty One Pilots will headline the opening night on 11th September. Known for their dynamic live performances and genre-blending style, the Grammy-winning duo are expected to deliver a set filled with fan favourites like Stressed Out and Ride, alongside tracks from their 2025 album Breach. Their booking underscores Sommo’s continued evolution as one of Eastern Canada’s premier live music events.

On 12th September, breakout pop artist Sombr will close the festival. The viral sensation, who skyrocketed to fame with the hit Caroline, is fresh off the success of his debut album I Barely Know Her. The record produced multiple chart-topping singles and has cemented his reputation as one of pop’s most streamed global artists, boasting over 53 million monthly Spotify listeners.

Originally launched in 2023 and later shifted to a September slot, Sommo Festival blends top-tier music with curated culinary offerings. Presented by the team behind Cavendish Beach Music Festival, Sommo continues to attract major international talent while highlighting the unique charm of Prince Edward Island’s North Shore. Tickets for the 2026 event are on sale now.
