The clip features Groban and "American Idol" winner Kelly Clarkson performing the Phantom of the Opera duet "All I Ask of You."
The forthcoming PBS concert, which was filmed in Los Angeles, is based on Groban's CD and concert tour of the same name.
"When I was making this record, and we were going to record this song, I knew this duet had to be recorded in a very, very special way and it had to be recorded with a very special singer," Groban previously said of Clarkson, according to Billboard. "She is one of the most versatile singers that I’ve ever heard."
