A Brand New Day

A Brand New Day is a song written by Sam Riegel and performed by the Bulgarian Symphony Orchestra and Trinity Boys Choir. It is played numerous times during Ace Combat 6: Fires of Liberation's campaign, appearing both in-game and during cutscenes. It was also played in trailers for the game and during the ending credits. It can be considered one of the game's main themes.

In When the Cold Breeze Blows Away, it could be sung by the How I Can Help Make the World Great guests when they're singing to the Golden King statue while the Emmerian tank is possessing it, and even while trapped inside the Gerasecian greater basilisk.
