The 2025 event added about 40 percent more space to the footprint of last year's Outside Festival; both nights felt about as packed as they could get, with estimated attendance levels surging from around 18,000 in 2024 to over 30,000 this year.

With just one main stage for larger touring acts, most of the weekend's earlier sets had a thirty-minute break in between, during which patrons could walk around and take advantage of the many rest lounges, VIP and general admission-plus spaces, and more. After a few laps around the massive sprawl of vendors, food trucks and workshop stages, I made it back to the main stage.Next up was Neal Francis, whose funk, R&B and soul influences were on full display as he ripped keys from behind his Hohner clavs. Vocally, Francis was a powerhouse performer and band leader, characterized by retro-sounding and soulful vocalizations, and drawn-out, neo-psychedelic jams atop thick bass grooves.

"Take care of each other. Free Palestine," Meath said, walking off stage to a cheering crowd.

Khruangbin's name means airplane in Thai, reflecting their deep musical influences from Thai funk of the 1960s and 1970s. The band discovered this genre while exploring global sounds, which heavily shaped their signature blend of psychedelic rock, funk, and soul.

Musical performances weren't limited to the main stage.

Sweden-based, Australian-born folk songwriter Hazlett took the stage at 3:45, with his trio of musicians offering a blend of poppy and twangy tones for a soft, heartfelt set filled with lyrical story songs and downplayed, pensive folk melodies. The vocalist known as Hazlett also said that his parents had flown all the way from Australia to catch the set, adding that their appearance at the packed fest "proved it wasn't a waste of time doing music."
Immediately following the Hazlett set, however, chaos ensued as thunderstorms and rain began pouring down ferociously, and messages appeared on the site's several massive LED screens warning of the inclement weather and telling patrons to "please calmly leave the venue through the nearest exit."

We were lucky enough to share the shelter with Brothers of Brass, whose portable brass band setup allowed the band to perform an impromptu set that saved the day and brightened everybody's moods. Despite the circumstances, the space was filled with laughter, dancing and celebration, as we awaited an all-clear in hopes that Waxahatchee would still get to play a set originally slated to start at 5 p.m.

After a rain delay, Waxahatchee performed before Trampled by Turtles on Sunday.

The band showed how rock and roll could sound atop Crutchfield's confessional, country-leaning songwriting, and her performance offered a captivating, warm-hearted way to reintroduce the music following an unexpected rainstorm, despite the set being shorter than planned. While the band's well-rounded sound shined on tracks like "3 Sisters," "Right Back to It," and "Much Ado About Nothing" from the 2022 album Tiger's Blood, my favorite moment was when Katie stopped the band mid-song to make sure someone could make it out of the pit safely — a real-life testament to the deep humanity in her writing.

The folk rock band was a fitting way to end a festival dedicated to getting outside, as Schneider sang several poetic tales about traversing lands, exploring other worlds, and searching for lost love on the journey.
"To the ends of the Earth would you follow me," Schneider sang on "Ends of the Earth."
"There's a world that was meant for our eyes to see."You can see additional photos from the 2025 Outside Festival and Summit below.

Lord Huron recently performed two nights at Red Rocks to celebrate his album Strange Trails 10th anniversary tour.
