Hopeful singers who missed out on “America’s Got Talent” auditions or a chance for a walk-on role on “Empire” will have another opportunity to try out in front of network executives. NBC is holding casting auditions next week for their upcoming TV musical, “The Wiz Live!”

The search is on for the next Dorothy, originally portrayed by Diana Ross in the 1978 Sydney Lumet film with Michael Jackson and by Stephanie Mills in the original Broadway production. Deadline reports the network is looking to cast an unknown for the starring role.

So, where and when can you show off your singing shops? NBC has announced it will hold auditions at Third Street Dance in Los Angeles on Monday, July 20. (New York locals had the chance to audition in June.) Singers must bring “an extraordinary voice” and “youthful energy” along with a few rehearsed songs from the original “The Wiz” stage musical.

And the musical fever has spread to yet another network. Fox will embark on its own Broadway venture when it premieres “Grease” live on Jan. 31, 2016. The musical will feature the talents of Keke Palmer, Aaron Tveit, Carlos PenaVega, Julianne Hough and Vanessa Hudgens. “Grease: Live” was first proposed in 2014, but the production is still casting a few more roles before its debut next year.

“The Wiz Live!” will air Dec. 3 at 8 p.m. EDT on NBC.
