Bluesfest Saturday lineup features Gwen Stefani, Shaggy, and Billie du Page on main stage

Ottawa Bluesfest's Saturday lineup on the RBC main stage opens with Billie du Page at 6 p.m., continues with reggae-dancehall legend Shaggy at 7:30 p.m., and closes with pop icon Gwen Stefani at 9:30 p.m.

Billie du Page, a Montreal pop songwriter, effortlessly weaves English and French over immaculate beats and hooks, offering the kind of bilingual grooves that capture a Saturday festival night as the sun sets. Shaggy's catalog extends far beyond his 1.4-billion-stream hit "It Wasn't Me," spanning tracks like "Angel," "Boombastic," and his 1993 debut "Oh Carolina." His trademark vocal style and dialect make him instantly recognizable across his entire repertoire.

Gwen Stefani transitions between genres with the ease of someone collecting challenges. Her No Doubt roots in ska punk gave way to pop success with hits like "Hollaback Girl" and "The Sweet Escape." Her newest album, "Bouquet," marks a shift into country, including a duet with her husband Blake Shelton. How that genre-spanning journey blends into Saturday's setlist will be worth watching.

On the Hard Rock Hotel & Casino Ottawa Stage behind the Canadian War Museum, Bridge Music opens at 6:15 p.m., followed by JUNO-nominated Toronto R&B artist Aqyila at 7:45 p.m., and Atlanta-based R&B powerhouse Mariah the Scientist wrapping at 9:15 p.m. Bridge Music, a local Christian-message R&B group named a Spotify Artist to Watch for 2025, brings nearly 10 million streams and their hit "Vulnerable." Aqyila's 2021 JUNO nomination came from "Vibe for Me (Bob for Me)," followed by JUNO award-winning "Hello" and her 2025 debut album "Falling Into Place."
