The first musical act to become established via Vine, Us the Duo comprises Michael Alvarado and his wife Carissa. This is the pair's first single since signing with Republic Records with the lyrics being an extension of the Alvarados' wedding vows.
The song features twice in the Fox animated motion picture, The Book of Life. Zoe Saldana, Diego Luna and Placido Domingo perform it during an important part of the movie, and Us the Duo's original version plays over the end credits. "Once we met the team and they heard our story, they were taken aback by how much our story was like the story in the movie - follow your passion, follow your heart," Carissa explained to Billboard magazine. "It's a dream come true to have a song in a move, so surreal to see it all happening."
