Altheimer Open-Air

30 Years of "total verROCKt!"

In 1996, the KLjB Altheim organized its first open-air festival under the motto "total verROCKt!" — a festival from rural youth for rural youth. Over the years, the festival has become a brand and now has supra-regional appeal. In 2026, the Altheimer Open-Air will celebrate its 30th anniversary. What hasn't changed: The festival is organized entirely on a voluntary basis by the KLjB youth — over 80 young people between 15 and 28 years old handle stage construction, technology, catering, security, and booking.

Between Cornfields and Forest

The festival grounds at Pfarrgasse 1 in Altheim (a district of Riedlingen) are located between cornfields and forest — an atmosphere that is central to the festival's identity. You won't enter an industrial area or a city square, but an agricultural environment transformed into a festival world for two days. It is precisely this rural charm that attracts a loyal audience every year.

Line-up 2026 — Indie and Alternative

The 2026 program features a mix of Indie Rock and Alternative on stage. Lonely Spring from Hesse are one of the most exciting German-language Indie Rock bands of the present day — melodic, intense, with lyrics between longing and self-reflection. Moonkid mixes Indie Pop with electronic elements. Malastaire provides the rock edge. An opener band will be confirmed in spring 2026, as will the Super Aftershow to conclude the festival.

Small, Voluntary, Honest

The Altheimer Open-Air belongs to that category of festivals that have become particularly valuable in the southern German festival landscape: small, voluntary, and not commercially oriented. The proceeds flow back into the association's work at KLjB. You won't experience a PR stunt here, but an event that thrives on the enthusiasm and commitment of young people.

Riedlingen-Altheim and Upper Swabia

Altheim is a district of Riedlingen — a town with a good 10,500 inhabitants on the Danube, in the Biberach district of Upper Swabia. The region between the Swabian Jura and Lake Constance is characterized by agriculture, with wide skies, rolling hills, and a strong tradition of village festivals. A festival visit can be well combined with a tour through the Danube floodplains or a detour to the nearby Bad Buchau.
