“He comes prepared,” the rock opera’s musical producer Harvey Mason Jr., 49, tells PEOPLE. “He’s doing a lot of different things right now, but he’s focused completely on this show. He knows the show inside and out and I’m really impressed with how diligently he’s working on stage with the cast and the director. It’s a lot of hours, but he’s dedicated.”
Because of Legend’s dedication to his craft, Mason Jr. considers the 10-time Grammy winner, 39, more than a musician. “He’s really a stylist in the way he sings,” Mason Jr. says. “That’s what makes this a special show and I think what’ll make his performance of Jesus special.”

“One thing we’re really proud of is the way that the cast is such a diverse group of people playing all different parts from different genres of music, different religious backgrounds and racial backgrounds,” continues Mason Jr., who worked on The Wiz Live! in 2015. “On the night that John or Sara puts their heart and soul into one of the performances, you appreciate it, you love it for what it is. You know it came directly from the artist’s soul.”
