Hinterland Music Festival has expanded its 2026 line-up with the addition of two more artists, welcoming Oklou and Wisp to the programme for next year’s event. The Iowa festival will return to Avenue of the Saints Amphitheater in St Charles from 30th July - 2nd August, 2026, continuing its tradition of blending major international names with rising alternative and pop talent across four days.

The newly announced artists join an already substantial bill led by KATSEYE, Lorde, Mumford & Sons, Kali Uchis and beabadoobee, alongside ASHNIKKO, MUNA, Wet Leg, Santigold, Jessie Murph and CMAT. Oklou’s ethereal electronic-pop sound and Wisp’s fast-rising shoegaze-influenced style further deepen the festival’s genre-spanning appeal, adding fresh texture to an already diverse 2026 line-up.

Hinterland has steadily built a reputation for curating emotionally resonant and forward-thinking line-ups, pairing established global acts with artists on the cusp of major breakthroughs. The addition of Oklou and Wisp reflects that ongoing approach, strengthening the festival’s alternative and experimental edge ahead of its return next summer.

Four-day tickets for Hinterland Music Festival 2026 are already on sale, with one-day tickets set to go on sale this Friday, 6th February, 2026 at 10:00am CT. With the line-up continuing to take shape, further announcements are expected in the months ahead.
