The original by Edge of Sanity released in their 1994 album “Purgatory Afterglow”, the clean vocals just doesn’t do it for me…
Heaven Shall Burn version released in their 2008 album “Iconoclast (Part 1: The Final Resistance)”
Eternal Tears of Sorrow version released in their 2000 album “Chaotic Beauty”, my favourite version…Awesome Solo!
