Huh. That’s cool. Medieval music has been a thing in Germany for many years (with relatively few pop covers though). From pure market-music (the kind played at medieval fairs), to versions with metal and/or electro elements.

Ougenweide [0] was one of the earliest in the 70ies, Zupfgeigenhansel [1] from the same time did some covers (Bella Ciao in German here)

Die Streuner [2] are not as close to the pure-medieval style but use a lot of self-built instruments.

Satolstelamanderfanz [3] are mostly instrumental and traditional, Corvus Corax [4] are similar, but far bigger, drum heavier, and also have a few covers.

Tanzwut [5] is an example of medieval electro-metal

Schelmish [6] is party-medieval music with metal influences, In Extremo [7] is probably the most successful medieval metal band.

I could probably go on for hours, but I think this is already a bit much, so I’ll stop here ;)
