Just as you can tell a story without sound, you can do the same for audio. After listening to Moon Graffiti on soundcloud, I now realize just how important sound is to telling a good story. All we had was people talking and the noises and sounds that were there but you felt as if you were on the moon while listening to it. It created the scene and you didn’t even have to see it. Sound can drive stories because it makes it feel like you are right there in the story and helps you create a better image and make it more memorable. There is a video about sound mixing https://www.youtube.com/watch?v=UO3N_PRIgX0 and this gives you a sense of how sound can bring a video to life.
