23rd Edition on Alperstedter See
In 2026, Stoned from the Underground celebrates its 23rd edition on Alperstedter See – a natural bathing lake in the Sömmerda district, 15 kilometers east of Erfurt. Since 2001, SFTU has established itself as one of the most important European festivals in the stoner rock scene. Radio BOB! has been a long-term media partner.
Stoner, Doom, Sludge, Psychedelic
The musical focus is on the subgenres of slow, heavy, and psychedelic rock: Stoner Rock in the tradition of Kyuss, Doom Metal in the vein of Black Sabbath, Sludge, Psychedelic Rock, and Space Rock. The festival is small, curated, and uncompromising in its selection – no mainstream, but depth.
Three Days of Camping by the Lake
SFTU is a camping festival: The grounds are located directly on Alperstedter See, and swimming is part of the festival routine. Several stages, a small number of visitors (not a mass festival), and a family-like atmosphere between bands and audience shape the mood.
Erfurt as the Arrival City
Alperstedter See is conveniently located between Erfurt and Sömmerda. Arrive by car via the A71, or by train to Erfurt (shuttle for the last few kilometers). Its location between forests and water in the Sömmerda district makes the festival the perfect summer getaway for lovers of heavy sounds.
