Underwood sang a sweeping rendition of the traditional Christian hymn "How Great Thou Art," hitting high notes that brought the crowd to a roar, and lead judging panel Lionel Richie, Luke Bryan and Jelly Roll to an emotional moment of worship. Backed by gospel singers and wearing an ethereal pink gown, Underwood smiled as she sang her song of praise, performing in front of a backdrop of dazzling, cloud-dotted skies. She let the song's message do the talking with a simple, clear delivery, rising to the emotional climax of "How Great Thou Art" with an extended high note and an expertly-delivered vocal run.
