Backdrop plans!
The great thing with this backdrop is that it looks really clean, but its not gonna cost a lot at all! I hope you caught on to the CD and cassette tape scheme. The name of your show (You were thinking Flashback), or your show choir name can be displayed on the CD like your the artist. Then, your high school name can be displayed at the bottom.
The first cassette tape (on the left) and the CD are attached. And there can be steps inbetween the CD and the Right cassette tape, that way you have an attractive entrance and exit. The steps cannot really be seen by the audience.
If you want, you can also put writing on the cassette tape, but that might not look very tidy. The idea is to keep it simple yet become outstanding.
I hope this works! I just made this site for temporary use cuz I dont have your email. When you get this, email me at singingmakesmehappy@gmail.com to tell me what you think! If you like it and your director and your class like it, then I can help you come up with a way of constructing it. It shouldnt be expensive at all.
