The Treasure Valley’s biggest one-day music festival is back — and the 15th annual Boise Music Festival is shaping up to be the best one yet. On Saturday, June 27 at Expo Idaho in Garden City, the festival runs a full day of live music and family entertainment from 10:00 AM to 10:00 PM.
The 2026 mainstage lineup features EDM superstar Marshmello, dancehall icon Sean Paul, alternative rock bands Everclear and Eve 6, and pop duo MKTO. Headliner Marshmello needs little introduction — with over 16.8 billion streams on Spotify, 68 million monthly listeners, and chart-topping collaborations with Khalid, Kane Brown, Selena Gomez, and the Jonas Brothers, he’s one of the biggest names in music and he’s never performed in Idaho — until now.
Beyond the mainstage, six total stages spread across the Expo Idaho fairgrounds showcase up to fifty local and regional musicians spanning acoustic, pop, country, bluegrass, folk, rock, hip-hop, and alternative. More than 40 food vendors, a vendor village with 100+ local artists and crafters, carnival rides, midway games, and family activities round out a full day that has something for everyone — whether you’re 8 or 80.
