ColdWorld combines atmospheric black metal with influences from ambient and electronic music, the centre stage takes the music with its sweeping melodies and icy atmosphere. ColdWorld's music forces fine-tuned listening and allows the listener submerge his/herself within a very special, cold world. ColdWorld leaves behind conventional, traditional black metal and brings forth new possibilities when it comes to song-writing and interpretation.
