Two of the biggest names in dance music just took over a ski mountain in the middle of summer. John Summit and Dom Dolla headlined Up In The Sky Festival in Aspen, Colorado, on August 7 and 8, 2026. Here's everything that happened, who else played, and why this lineup was a bigger deal than it might look at first glance.

When and Where

This was the festival's second year. It's held right at the base of Buttermilk, one of Aspen's ski mountains, so fans got mountain views instead of a flat festival field.

The Full Lineup

Friday, August 7 — headlined by John Summit

Saturday, August 8 — headlined by Dom Dolla

Who Are John Summit and Dom Dolla?

John Summit is from Chicago, the city where house music started. He used to work as an accountant before music took over. His song "Deep End" blew up in 2020 and became one of the biggest dance tracks of the year. Since then, he's turned into one of the most in-demand headliners in the world, and he's set to close out the main stage at Ultra Music Festival in 2026, one of the biggest honors a dance artist can get.

Dom Dolla is a producer and DJ from Australia. He makes house music that's built for huge crowds, with basslines that hit hard but stay catchy. Over the past few years, he's gone from club shows to selling out stadiums and headlining major festivals around the world.

Why Pairing Them Was a Big Deal

John Summit and Dom Dolla aren't just two random headliners. In 2025, they launched a joint touring series together called Everything Always, where they play back-to-back sets as a duo. It's become one of the most talked-about pairings in dance music, so seeing both of their names on the same poster, even on separate nights, was a big draw for fans.

A Sign of Where Dance Music Is Headed

This lineup also marks a real shift for the festival itself. Up In The Sky's first year, in 2025, was headlined by Kacey Musgraves and Rüfüs Du Sol, a mix of country and indie-leaning electronic music. Going all-in on John Summit and Dom Dolla for year two shows how far house and dance music have pushed into the mainstream. Festivals that used to lean on pop, country, or indie headliners are now building entire lineups around DJs, and Aspen is just the latest place proving it can sell tickets that way.
