I couldn't tell from the video where the sound was coming from. If it comes from the yard, the neighbors really hate him. There is a house in my town that does a similar choreographed light show but not nearly as large. He has a sign in his yard that says tune to 88.7 or so. He broadcasts the music over radio so he's neighbors dont have to listen to it over and over. His lights also turn off at around 10pm. I think it's cool you can program lights to sync with a music track but I'll find a better use and be a better neighbor.
