That's not a Prussian song. That's a Lithuanian neo-pagan band performing a completely original orchestration of a 19th century Lithuanian poem the band writer translated into Old Prussian.While waiting on that, here's Prussian theme source (or at least part of it) - Zeminnika kweitākedi
Now that's....unexpected. A modern rendition of an Old (Baltic) Prussian folk song from pre-Teutonic times.
From their own description: Tekstas į senąją Prūsų kalbą išverstas iš Rytprūsiuose Liudviko Rėzos išleisto lietuvininkų liaudies dainų rinkinio 84-tosios dainos; pointing to https://archive.org/details/dainos00reza/page/226/mode/2up for the Lithuanian poem they used as a base.
