The song "Sol Invictus," from Thea Gilmore's 2009 album Strange Communion, was the product of a creative collaboration between Gilmore and Jennifer John.

Thea Gilmore composed and wrote the lyrics for the song, creating the framework and core message of the haunting, pagan-inspired piece.

Jennifer John, as both a vocal arranger and director of Sense of Sound choir, composed the specific, intricate choral parts that gave the song its spine-tingling a cappella performance.

Sense of Sound, under Jennifer’s direction, performed the vocal arrangement, executing the layered harmonies and hymnal atmosphere.
