This is a cover version of Tarja's I Walk Alone by Jørn Lande. He is a Norwegian heavy metal singer and does the lead vocals in German power metal band Masterplan and of course in many other bands.
I am not really against covers and this one sounds pretty "heavy" which I like. Yet my ears suffer a little bit when Jørn sings "I walk alone" and "My winter storm" lines.
All in all I think it's a good cover, but I don't listen to it often.
