“War” is a song from a larger work. This particular release is put together by two parts of the “War” theme that occurs on different places in the larger work.
The concept of these songs, (including the song “War”) was supposed to reflect on classic reasons for conflicts, which usually can be solved through communication. And how they are based on common human feelings (love, worries, ambitions, and regrets etc.)
“War” refers to all kinds of small and big conflicts and threats. Those amongst people, but also the ones we have with ourself in our own minds. And how similar they all are to all of us.
