Neil Davidge: Halo 4 Original Soundtrack - an album guide

15. Green and Blue
The final track from the album is being released as a single, and features a gorgeous cello solo from London Contemporary Orchestra cellist David Cohen, as Neil Davidge explains: "This is an emotional, beautiful, rich and very human composition. It’s one of my favourite pieces from the score and was also the very first orchestral recording that we made at Abbey Road studios for the game."
