Aspen has never needed much help convincing people to visit. The mountain views, food, outdoor recreation, and cultural history have made it one of Colorado’s most recognizable destinations for decades. Still, much of that identity has traditionally revolved around winter. Up In The Sky is helping expand that picture.
Returning to the base of Buttermilk Mountain on August 7 and 8, the festival brings together world-class music, wide-open scenery, and the kind of destination experience that can only exist in a place like Aspen. Now entering its second year, Up In The Sky is still young, but its identity already feels distinct. It is polished without losing intimacy, ambitious without trying to become oversized, and deeply connected to the place surrounding it.
The inaugural edition proved that the vision could work. It also gave organizers the kind of education that can only come from watching thousands of people move through a festival in real time. Transportation, crowd flow, arrival patterns, and the rhythm of the site all revealed details that no planning document could fully predict. Year two is not about rebuilding the concept, but refining it through experience.
At the center of that concept is Buttermilk itself. The festival grounds sit at the base of the mountain with sweeping views across the Roaring Fork Valley, creating a setting that feels inseparable from the event. The surrounding landscape does more than provide a dramatic backdrop. It shapes the entire atmosphere, from the pacing of the day to the way each performance lands as the light begins to change.
That sense of progression is reflected in the 2026 lineup. John Summit and Dom Dolla headline a bill that moves across electronic music, indie, alternative, R&B, and live-band performance without losing its cohesion. Empire of the Sun, Parcels, Leon Thomas, Polo & Pan, Passion Pit, and others give the weekend range, but the intention is not simply to place unrelated genres beside one another. Each day is designed to build toward movement.
Live acts and rising artists create the early texture before the energy gradually shifts toward the dancefloor. By night, the festival transforms into a full-scale dance party, allowing electronic and live performance to complement one another rather than compete for attention. The result is a lineup that feels broad without becoming scattered.
That balance reflects the partnership behind the festival. Belly Up Aspen has spent years bringing major artists into one of the country’s most intimate and respected venues, developing a deep understanding of the local audience and what makes live music in Aspen resonate. C3 Presents brings the knowledge gained from producing some of the largest festivals in the country. Together, the two organizations are learning how to grow the scale of the experience without losing the closeness that has long defined Belly Up.
In a crowded Colorado festival landscape, that intimacy matters. Up In The Sky is not trying to imitate the state’s larger camping festivals or urban concert weekends. Its appeal comes from being specific to Aspen. The mountain setting, hospitality, music, and surrounding town all become part of the same getaway, giving attendees reasons to explore beyond the festival gates.
That destination appeal is balanced by an equally strong connection to the Roaring Fork Valley. Discounted local tickets reflect more than a marketing strategy. For the Goldberg family, this is home, and keeping the event accessible to the people who live in the area remains a fundamental principle. The festival may attract travelers from around the country, but it cannot succeed long term without feeling like it belongs to the local community as well.
That same duality appears throughout the ticketing experience. General Admission offers access to the full weekend, while VIP and Cabin packages provide elevated hospitality, private spaces, curated food, and enhanced viewing. Those layers allow the festival to serve different types of attendees while keeping the central experience rooted in the music and setting.
As Up In The Sky looks toward the future, the goals are both expansive and grounded. The team wants longevity, cultural impact, and a permanent place on Aspen’s summer calendar. They also understand that traditions are not created through ambition alone. They are built through consistency, attention to detail, and the willingness to improve every year.
For now, the focus remains on embracing the second edition rather than rushing past it. A festival of this scale requires thousands of hours and hundreds of people, yet the weekend itself disappears quickly. Up In The Sky may have big plans for what it can eventually become, but its founders are also learning to slow down long enough to appreciate what they have already built.
We caught up with Up In The Sky founders Danny and David Goldberg to talk about the lessons of year one, Aspen’s growing identity as a summer music destination, and what it takes to build a festival that feels both ambitious and intimate. Check out our conversation below!
[Rooster]: Up In The Sky arrived last year with a pretty ambitious vision. Now that you’ve had a full year to reflect on the inaugural event, what did you learn from year one that shaped the way you’re approaching the festival in 2026?
[Danny and David Goldberg]: There’s a whole layer of details you can only learn by doing the event. Logistics, transportation, and the flow of people on site are things you can plan for on paper, but the real education happens when you’ve got thousands of people there and you’re seeing it play out in real time.
Aspen has long been known for world-class skiing, food, and culture, but it feels like it’s increasingly becoming a serious summer music destination as well. Why do you think Aspen is such a compelling place to experience live music right now?
Winter obviously gets a lot of attention, but if you’ve ever spent a summer in Aspen, you know it’s one of the most beautiful places on earth with a lot of summer activities. You add that with a ton of great music and it becomes even more compelling to come here and see music.
This year’s lineup bridges electronic, indie, alternative, and live-band worlds. What was the thought process behind bringing those artists together?
It was a conscious effort to make the lineup diverse, with a consistent desire to have dance music, both live and electronic, well represented. As the nights progress, we want them to turn into a dance party.
The setting at the base of Buttermilk is a huge part of the experience. How much does the surrounding landscape influence the festival’s identity?
The site itself is everything for this festival when it comes to the experience. The scenery, with a stage at the bottom of the mountain and views of the entire Roaring Fork Valley, is truly stunning and really plays into our identity.
Festivals are competing for attention more than ever. What makes Up In The Sky distinct from other events happening across Colorado?
Every festival has its own distinct feeling and offering. We are focused on creating a unique experience with great artists, both established and up-and-coming. We work hard to create a well-organized and properly executed event where people can make memories with friends and family.
How has the combination of Belly Up Aspen’s local knowledge and C3 Presents’ large-scale expertise shaped the festival?
We are very close with them. They’re some of our best friends, and we are partners in other businesses as well. Being like-minded and able to rely on and learn from each other has been a major benefit. We are always striving for an intimate feeling, and collaborating to maintain that while growing the magnitude has been a fun experience.
How important is it to balance the festival’s destination appeal with keeping it connected to the local community?
This is our home. Doing things in that spirit will always be part of all our businesses, and it is absolutely a fundamental principle for us. That won’t ever change.
When you think about the future of Up In The Sky, what does success look like?
All of the above. We love the impact this makes on the valley culturally and economically, and hopefully someday traditionally as well. Longevity is something we are striving for, but we’re also focusing on the little things and trying to remain in the moment. It takes thousands of hours of work by hundreds of people to pull this off, and it’s gone very quickly. While we love to think big and look forward, we’re trying to find as many ways as possible to slow this one down and take it in.
