This is truly amazing.

A video posted to YouTube Thursday shows former secretary of State Condoleezza Rice on piano accompanying Utah violinist Jenny Oaks Baker in a spectacular rendition of "Amazing Grace."

The song is for sale on iTunes. According to Fox 13 Salt Lake City, the money raised by sales of the tune will go to the Wounded Warrior Project.

"It was such a joy and a privilege to perform 'Amazing Grace' with Dr. Rice," Baker explained of the collaboration. "It is my favorite song to perform and I am thrilled that we are able to pay tribute to all the soldiers who have given so much for America."
