As is often said about great figures in history who have passed away, their legacy transcends them and in that sense they are still 'alive' every time they are remembered. This got me thinking, what if every time I listen to a musician who is dead, they are alive somewhere else, in another dimension or universe, performing that song just for me? My concept is this - my main character somehow stumbles upon a large waiting room (imagine an airport gate, or a waiting room in a large train station) where all of the musical greats who have died are gathered and sitting around, chit-chatting and passing the time just as anyone would who was waiting in a large waiting room. Every so often, one of them is 'called' and they pick up their instruments and head down the gate, as though they were getting on a plane or train, but in reality they are going to perform for someone who has...say...selected them on their iPod or popped in a DVD of a concert. I don't know where to take this idea or what to do with it. How has my main character found himself in this waiting room? How does the story progress? In what dimension is this waiting room located? How do Miles Davis and Kurt Cobain get along while sitting next to each other? Any ideas or tips for strengthening this story would be appreciated.
