The Soundside festival, a well-celebrated event in the musical calendar, will once again take place in Bridgeport, Connecticut. Scheduled for September 27 and 28, 2025, the festival marks its return to Seaside Park with a promise of unforgettable performances from an eclectic mix of artists across various genres. Established by C3 Presents, this festival has quickly gained popularity thanks to its deft blend of artists making waves in alternative, Americana, indie-rock, pop, and folk music. This year features a phenomenal lineup led by prominent performers such as The Killers and Hozier, who are known for their engaging live shows and mainstream success.

The first day of Soundside will spotlight The Killers as the headlining act, further validating the festival's reputation as a premier rock music event.

On the second day, Hozier will lead the lineup, returning after a praised performance at Sound On Sound. His deeply soulful voice and thought-provoking lyrics are set to captivate the audience. Vampire Weekend will follow up with their critically acclaimed band, keeping the momentum high. The day will also feature electric performances by The Backseat Lovers and Remi Wolf, cementing the festival's reputation for mixing veteran talent with rising stars. The addition of acts like Chelsea Cutler and Alex Warren enhances the day’s appeal, promising a rich canvas of sounds and styles for attendees to enjoy.

Music festivals like Soundside have become hotspots for discovering new artists, and the 2025 lineup bolsters this trend.
