Pharrell Williams and Andrea Bocelli are co-directing a concert set to take place in the heart of Vatican City. The “landmark cultural and spiritual event” will take place in St. Peter’s Square and mark the closing of the third World Meeting on Human Fraternity with support from the Vatican. There will also be an aerial drone and light show by Nova Sky Stories, including imagery inspired by the Sistine Chapel. Williams called the upcoming gathering “a rare cultural moment where the world stops and collectively tunes in. It is a message of unity and grace for all of humanity,” per the release.
