Williams shows his "Carnival Heart"

He created the original track as the official anthem for the new country-themed show, Songblazers: A Journey Into Country Music, produced and presented by Cirque du Soleil and Universal Music Group Nashville.

Written and directed by Amy Tinkham, Songblazers opens in Nashville this July with seven additional cities following the launch.

Williams said, "I love painting a picture and causing curiosity in someone about a character or story. Getting to be part of this and collaborate with such world-class entertainers is a blessing. 'The New Nashville' is coming, and it can honor the past and point towards the future. I always wanted to be a professional freak."

Co-written by Williams with PJ Harding and Ned Houston, acoustic strumming sets the tone in between the echoes of slide guitar.

"I've written very sad songs in my time, and I was able to write this from a true place of acceptance and triumph over pain," Williams said. "'Carnival Heart' mirrors a lot of my struggles as well as the journey of trying to find myself over the past several years. It talks about not knowing where your home is and wondering if the old innocent dreamer version of yourself is still there. Life is a crazy and beautifully painful roller coaster and you have to just ride."

Williams recently released the duet with Carter Faith "'Til I Can Make It On My Own."
