It is part of the OST that will be in the game. loving everything I've heard so far I'm really digging the music and just about everything I've seen and heard. Witcher 3 is without a doubt my most anticipated game of 2015 ( was for 2014 before the delay as well.)

Percival - 'Percival was formed as a result of our fascination with history, experimental archaeology and historical reenactment. We want to spread knowledge of our Slavic history and the traditions of people who lived in the Baltic Sea area.
We sing old Slavic melodies as well as our own compositions - they create the atmosphere of ancient times and bring listeners back to the Early Medieval world. '
