A new musical gem is landing in Aspen, Colorado, and it’s set to elevate your summer plans. The inaugural Up In The Sky Music Festival, happening August 8-9, 2025, at the base of Buttermilk Mountain, promises an unforgettable weekend with electronic trio Rüfüs Du Sol and country star Kacey Musgraves headlining the lineup. Brought to you by CapitalCityTickets.com, here’s everything you need to know about this breathtaking debut event.

A Star-Studded Lineup to Kick Off Day One
Day one, Friday, August 8, ignites with Rüfüs Du Sol, the Australian dance sensations known for hits like “Innerbloom” and “You Were Right.” Their pulsating beats and immersive live performances have made them festival favorites worldwide, and their Up In The Sky set is poised to electrify Aspen’s mountain air. Joining them are Glass Beams, Suki Waterhouse, and SG Lewis (Live), blending psych-rock, indie vibes, and electronic grooves for a dynamic opener. This multi-genre mix sets the stage for a festival that defies boundaries.
Kacey Musgraves Closes Out Day Two
On Saturday, August 9, Grammy-winning Kacey Musgraves takes the spotlight, bringing her soulful country-pop sound to the Rockies. Fresh off hits like “Golden Hour” and “Deeper Well,” Musgraves’ heartfelt lyrics and dreamy melodies will pair perfectly with Buttermilk’s panoramic views. The day also features indie rockers Glass Animals, alongside Role Model, Nessa Barrett, and Jensen McRae, offering a rich tapestry of singer-songwriter and alternative talent. It’s a lineup that promises something for every music lover.
Why Up In The Sky Stands Out
Produced by Belly Up Aspen and C3 Presents—veterans behind Bonnaroo and Lollapalooza—Up In The Sky Music Festival isn’t just about the music; it’s a getaway. Nestled at the base of Buttermilk Mountain, the venue offers stunning vistas, making it as much a feast for the eyes as the ears. From electronic dance to country and indie, the festival’s eclectic roster reflects a growing trend of genre-blending events that appeal to diverse crowds. CapitalCityTickets.com highlights this as a can’t-miss experience for 2025.
