Blackdoor Reflections Indoor Festival

Stoner and Psychedelic in the Snow

While the large Blackdoor Music Fest attracts open-air lovers of heavy, psychedelic sounds to Thyrnau every summer, there has been a much more intimate indoor edition in winter for several years: the Blackdoor Reflections. In 2026, the edition will take place on January 9th and 10th at the König-Max-Höhe in Thyrnau (Kellberg district) and will bring two days of concentrated heavy sound across two stages.

International Top of the Stoner Scene

The 2026 lineup is exceptionally dense: Black Rainbows (Rome) as an Italian stoner institution, Nightstalker (Athens) as a Greek legend, Dÿse as a German heavy duo, Godsleep, Dirty Sound Magnet from Switzerland, Temple Fang (NL), Acid Mammoth, Skraeckoedlan (SE), Kant, Ultima Radio, Savanah (Graz, AT), Ozymandias, Lazer, and Mad Mother. Genres: Stoner Rock, Heavy Psych, Doom, Desert Rock, Sludge.

Indoor Concept and Art Moment

In contrast to the summer main edition, Blackdoor Reflections takes place entirely indoors. Two stages ensure seamless program changes, and the concept is complemented by conceptual art elements and a curated atmosphere. "Familiar faces, new setting, a touch of conceptual art" – this is how the organizers themselves describe the Reflections edition.

Thyrnau in the Passau Region

Thyrnau is located about 12 km northeast of Passau in the Passau district (Lower Bavaria), in the western foothills of the Bavarian Forest. The Kellberg district is a climatic health resort, and its location between the Danube and the Czech border makes it an attractive destination for guests from Austria and the Czech Republic. With the Blackdoor Festival, Thyrnau has established itself in the heavy music scene as a destination that combines an idyllic location with hard sounds.
