This is an intriguing idea. A bored, though successful, musician finds a way to be inspired. While he is performing on an island (somewhere in the Caribbean), his drummer begins to act oddly. Our man follows him one night and sees that he is participating in a voodoo ceremony. He hears them playing music that is stuck in his head and he now has purpose. Unfortunately, he is captured while listening and made to promise, on his life, to not reveal anything he has heard. Of course, he ignore their wishes and that's that. He writes a piece called Voodoo Rhapsody which is immediately embraced. The problem is that he suddenly is beset with pain and angst and his career falls apart. I won't ruin the plot, but we don't need to think to much to understand how things play out. I've never really understood the whole voodoo thing, but from all the films and shows I've seen, I wouldn't mess with it.
