I currently have about 3 different concepts and synopsis' for original musicals. If I get further along, I may share. But, people, come on now. Original Musicals need a come back! Not biographies and musicals based on movies!
I think a legitimate musical inspired by the life and career of Britney Spears could be great source material using her music. I can see it now: "Lucky - The Musical." Not gonna lie, I assembled an iTunes playlist with characters and scenes and stuff.
