Like the idea of a space themed dance, there is a lot you can do with it. will you have a projector playing videos and such (the audio visual part)?

You need some sort of narrative to play for the dancers, as you journey from ground control to the deep parts of our galaxy. Think something like morgan freeman or david attenburgh narrating. Have different speeds of music to go alongside differnt parts of your journey etc. One song that you could use part of is Bass head, by bassnectar. A great tune, more drum and bass but I thiink it would work well. skip to 40 seconds in to see the part that resembles take off.here is the link
