Medieval music has something mysterious. The sounds often appear unusually foreign to modern ears, just like the historical instruments. When it comes to performance practice, one quickly encounters the limits of musicological research because many aspects cannot be clarified due to the temporal difference. In addition, there is a relatively limited amount of surviving material. The notation, like other written literature of the time, was transcribed by hand for a long time, making it very precious, and today, it is only preserved in sometimes fragmentary manuscripts. A large part of the music is no longer accessible today because it was transmitted solely orally.

The very mysterious, unknown, and incomplete nature of medieval music has, in modern times, inspired many composers, including ensemble feuervogel, to continue working with the material. It is precisely the gaps in transmission that create space for individual interpretations and experimental exploration.

'Medieval Nights' presents a selection of historically transmitted musical pieces in unique arrangements, as well as modern compositions that incorporate musical material from the Middle Ages. The result is an atmospheric, surprising program with a trance-like character.
