How could a band like InEx just fall into the past without any attention?
Very very sad.
They are a well known german band. They've also won the "Bundesvision Songcontest", which is like the Eurovision, just inside of Germany, as we have 16 different states.
They actually mix metal with folk and started their carreer as a folk band without any rock or modern instruments in there. When they started they used to play old and well known medieval songs, like ai vis lo lolop, poc vecem, or Herr Mannelig (which is an old swedish song)
So the band mixes a lot of languages, even languages which are not spoken anymore, like gallic, old-german, latin, oldschool swedish, etc.
