Caleb Grimm (from Anthem Lights) tag teams with fellow singer Kelsey Grimm for a cover of Shoulda Been Us from Tori Kelly.
Their voices go really great together. They blend so well for this duet, it is very impressive. The background music they put with it has a piano carrying the melody to produce some very awesome music to go right along with their singing. It is such a great song!
