Summer Camp Music Festival has announced its initial artist lineup for the 2026 edition, scheduled for May 21-24 in Chillicothe, Illinois. The festival will mark its 25th anniversary with performances from STS9, Two Friends, EOTO, Big Gigantic and dozens of additional acts.

The four-day event returns to its traditional venue at Three Sisters Park in Chillicothe. Organizers confirmed the first wave of performers through social media channels and the festival’s website earlier this week.

STS9 will make their return to Summer Camp alongside electronic duo Big Gigantic. Two Friends and EOTO round out the top tier of announced acts, with more artists expected to be revealed in coming weeks.

The milestone anniversary comes as Summer Camp continues to establish itself as one of the Midwest’s premier music festivals. The event has grown from its humble beginnings in 2001 to now hosting thousands of attendees each Memorial Day weekend.

Tickets for the 2026 festival go on sale Friday, with various camping and lodging packages available. Early bird pricing will be offered through the end of January, according to festival representatives.
