New Music: Mariah Carey f/ Patricia Carey - 'O Come All Ye Faithful'

For Mariah Carey, Christmas is a family affair on the delicate ballad “O Come All Ye Faithful / Hallelujah Chorus,” the highly-anticipated duet with her opera-trained mom Patricia Carey from her holiday album Merry Christmas II You (Nov. 2). With a full backing choir, the gospel-tinged number features inspirational vocal trills from Mariah, who flips it over to her mom before joining back up with her for an explosive climax near the end. Spend an early Christmas with the Careys below.
