Show effect

Last night I was playing my guitar and I saw this shadow in my wall. I found it interesting. I had little desk light behind of me. Tugsten light. I would like to create this kind of effects for a show. Maybe in front of a curtain before to open a show. I could use a backlight, shooting white light behind the artist and proyecting his shadow on the curtain. The people in the other side of the curtain could see his shadow. It could be a easy and a nice effect for a show.
