The traditional Gasthof Blaue Quelle in Erl dates back to the 17th century and was named after the "Blaue Quelle" (Blue Spring), Tirol’s largest source of potable spring water. The spring, which is protected by nature conservation legislation, bubbles up from within a mountain and has a flow rate of 700 liters per second. Every Thursday during the Festival, Gasthaus Blaue Quelle plays host to familiar works that experienced a charming revision à la Erl and thus open up new perspectives. 
Artists who performed at the Blaue Quelle include Akkosax, Gunter Schneider, Barbara Romen and Gregor Mayrhofer.
