“The Jesus Music” explores the often-untold roots of contemporary Christian music, featuring interviews with some of the biggest names in the genre, including Amy Grant, TobyMac, Kirk Franklin, Lauren Daigle and Michael W. Smith, among others.

According to an official film synopsis, “the universal power of music from these artists shine through from their messages of passion, sacrifice, and redemption that inspire millions of devoted listeners.”

“The richness of hope that can lead on someone’s spirit via rhyme and melody and sound, I don’t understand it,” Daigle opens up in the documentary trailer.

Amy Grant reveals what moved her to contemporary Christian music.

“A lot of hymns are ‘close your eyes singing to God,’ I wanted to sing with my eyes wide open, singing to each other,” Grant said.

“Everything felt so fresh and new,” Grant added when talking about the genre’s growth in the early ‘70s.

The documentary is directed by the Erwin Brothers, who brought us films like “I Can Only Imagine,” “I Still Believe,” and “American Underdog.” The film also features interviews from major faith and contemporary music figures, including Glen Kaiser, Greg Laurie, John Thompson, For King & Country, Chris Tomlin, Bill Gaither and Bill Reeves.
