For the past three years, the Soundside music festival (formerly Sound on Sound) has delivered stadium-level headliners (Red Hot Chili Peppers, Stevie Nicks, John Mayer, to name a few) as well as local Connecticut acts (Deep Banana Blackout, Drew Angus) and up-and-coming artists that have since blown up in popularity (Noah Kahan, Zach Bryan). This year —when the festival returns to Bridgeport's Seaside Park for its fourth year on Saturday, Sept. 27 and Sunday, Sept. 28 — will be no different, but with a bit of an early aughts slant.
Behind booking what he describes as a "heavily curated" lineup at Soundside is Live Nation's lead booker Bryan Benson. Outside of Soundside, Benson has his hand in booking Live Nation lineups around the country including High Water Fest in South Carolina, Bonnaroo in Tennessee and Boston Calling in Massachusetts.
Unlike the aforementioned festivals, which are anchored by multiple stages and can feature more than 100 artists, Soundside features one rotating stage with only 10 artists per day.

"Given the site that we have...it sort of lends to a lineup that's very heavily curated, ideally to a fairly specific fan that's going to be into coming out and seeing what we have," Benson said.
This year's lineup is led by arena rockers The Killers on Saturday and popular folk rock artist Hozier, who is returning to Seaside Park after performing at the festival in 2023. Other notable acts performing in 2025 include Weezer, Vampire Weekend, Djo, The Backseat Lovers and Remi Wolf.
Cohesion is the key to the lineup, Benson said, even though genres in this year lineup range from the folk-pop of TikToker Alex Warren to the '90s and 2000s rock sound of Weezer. Though Benson said it's not a "headliner-driven game," he said it's helpful to know who the headliners are in order to curate the rest of the day.
"If you're a fan of Hozier or The Killers or Vampire Weekend, we've got a lot on each day for you to sink your teeth into that you're probably going to be pretty excited about," Benson said.
As with previous years, artists on the top lines of both days at Soundside are veteran bands like Vampire Weekend and The Killers who rose to prominence about 20 years ago and Weezer who released its "Blue Album" 31 years ago with hits like "Buddy Holly" and "Say it Ain't So."
"To me, The Killers isn't that far of a departure from Stevie Nicks and John Mayer," said Benson.
But for every artist with a storied career, Soundside is booking up-and-coming artists that have only continue to grown in popularity since their booking. Benson cited artists like Alex Warren, Rachel Chinouriri, The Last Dinner Party and Djo (Joe Keery) as artists that the team needed to get a jump on or else they "wouldn't have had accessibility to them."
"Sometimes you just got to take a swing on something that, you know, you may or may not know what is going to feel like in September," Benson said, adding that artists are planning their touring further out in advance lately, which is a "challenge we accept as festival booker."
Someone who has grown since last visiting Bridgeport is Hozier, who topped the charts in 2024 with his single "Too Sweet," which was released after his Sound on Sound performance in 2023. For Benson, Hozier is a "bullseye" for what they are attempting to do with booking at Soundside.
"If you're trying to follow up Noah Kahan from last year, Hozier to me is the perfect bridge to that fan," Benson said, adding that "his fanbase ... spans across the board."
In addition to booking according to wide popularity, the festival is "focused in terms of an audience and demographic," catering to Fairfield County residents while still pulling music fans from far away.
While the festival has seen great success, breaking its own attendance record last year with 57,000 attendees, it also faced some headwind last year with its lineup. Due to injury, Queens of the Stone Age had to drop out in August and was replaced by Bleachers. Then with only two days left until the festival was set to kick off, Foo Fighters, who were initially tapped to close out the festival on Sunday, dropped out.
"A headliner pulling off your show a week out is nothing you prepare for," Benson said, adding that it was the only time an occurrence like this has happened to him. The festival turned around the same day and announced Jack White and Greta Van Fleet as co-headliners for the final day of the 2024 festival.
"I felt we handled it really well and got two bands to replace one, and did the best we could and still delivered a great show for those folks," Benson said.
Benson said plans are already in motion to book for the 2026 edition of the festival with the team already beginning to put out feelers for what music will bring fans back to Seaside Park.
