Been looking for months for this ost and Finally found this place, found at least 3 links but are all dead. I really enjoyed the music in the movie especially S�kkij�rven Polkka, that scene was Epic!
If anyone has a link, please do refer me one.

If MP3 suits you, you can find it here (https://mega.nz/#!Ql4hmTjJ!nlhGNB5WA8AIDW7ZIWr-C3oHcMpgBlaoh-9uctOux1M).
All credits goes to Bal-Sagoth from Nautiljon website.

Enjoy!

Wow Thanks!
