Aspen's Up in the Sky Festival Transforms Buttermilk for Electronic Music Fans

Aspen —The bass vibrated through the soles of boots planted on the high alpine tundra. It was August 7, 2026, and the snow had long since melted from the Buttermilk Ski Area slopes, replaced by a sea of bodies and festival gear.

The Up in the Sky music festival returned to this Aspen landmark, transforming the familiar ski runs into a sprawling electronic music venue. The event drew crowds who braved the altitude for a weekend of electronic beats, headliners, and the distinct, thin-air energy that only a mountain festival can provide.

Photographs captured the scene in vivid detail. Attendees danced with abandon as the band Fcukers took the stage, their performance punctuated by the rhythmic thump of drums and the swell of synthesizers. One woman moved to the beat, her silhouette framed against the backdrop of the performing act. The energy was palpable, a stark contrast to the quiet, snowy solitude that defines Buttermilk for most of the year.

John Summit, the headliner, brought his signature catchphrase to the crowd. An attendee held up a handmade sign that read, “Aspen how tf we feelin’ baby?” — a direct nod to Summit’s popular phrase. The sign became a focal point in the crowd, a small piece of cardboard signaling a shared understanding between the artist and the audience. It wasn’t just about the music; it was about the collective experience, the shared language of the festival circuit.

Empire of the Sun also delivered a set that drew significant attention. The band performed multiple times throughout the day, their music weaving through the afternoon heat. The photos show the band in action, instruments in hand, lights flashing, and the crowd responding with equal fervor. The repetition of their performance underscores the festival’s structure — a curated experience where established acts anchor the lineup, drawing in fans who might not have come for the deeper cuts or the opening bands.

Austin Colbert, the photographer for The Aspen Times, documented these moments. His images show the scale of the event. People are scattered across the frame, some close to the stage, others further back, all united by the sound. The setting, Buttermilk Ski Area, adds a layer of visual interest. The ski lifts stand idle in the background, silent sentinels watching the transformation of the mountain into a music venue.

The festival took place on a Friday, allowing attendees to start their weekend early. The date, August 7, 2026, marks a specific moment in Aspen’s cultural calendar. It’s a time when the town, usually dominated by ski tourism in the winter and hiking in the summer, pivots to embrace its nightlife and music scene. Buttermilk, often overshadowed by its neighbor Aspen Mountain, serves as a unique venue. It’s larger, more spread out, and offers a different kind of mountain experience; one that is less about the vertical drop and more about the horizontal expanse of the crowd.

The presence of Fcukers and Empire of the Sun suggests a lineup aimed at a broad electronic music audience. These are not niche indie acts; they are mainstream electronic artists with established fanbases. The festival leverages their popularity to draw in visitors who might not otherwise visit Buttermilk in the late summer. The sign reading “Aspen how tf we feelin’ baby?” is more than just a joke. It’s a reflection of the headliner’s influence and the audience’s engagement. It’s a moment of connection, captured in a photograph, that speaks to the larger event.

The images show a crowd that is engaged, if not always focused. People are dancing, holding up signs, and soaking in the atmosphere. The weather appears clear, typical for an Aspen August. The sun is high, casting long shadows from the ski lifts and the stage structures. It’s a scene of controlled chaos, of music and movement and mountain air.

This return to Buttermilk is significant. It’s not just another festival in the valley. It’s a reclaiming of space, a temporary repurposing of infrastructure that serves the community in different ways at different times of the year. The ski area, usually a place of athletic endeavor, becomes a place of artistic expression. The contrast is striking, and it’s this contrast that makes the event memorable.

The photos by Austin Colbert serve as a visual record of this transformation. They capture the essence of the Up in the Sky festival, the music, the crowd, the setting. They show a community coming together, if only for a weekend, to celebrate sound and light and the unique geography of Aspen. The sign, the dancing, the performance - it’s all part of the same story. A story of a mountain, a festival, and the people who fill the space between them.
