This song is from the album Red vs. Blue Season 13 Soundtrack.

From RVB13E16. Nico: this was one of those moments where Levy and I really connected, even though we work remotely. Miles took us by surprise as much as anyone else with this episode. Levy came up with the groove and architecture of the tune, which to my ears, sounded like something Trocadero would do -- a simple building progression with cool soundscaping. I added the bass, and in turn wrote a guitar part that was pretty violin-like.
