Ok, i saw this movie a handful of times, but was usually a bit drunk whilst watching it. I'm 99% sertain it was a late 70s flick, about the time the first Halloween came out, about music, or some demonic band. The one sceen that surfaces the most from the foggy mush on my memories is a teen girl in the back seat on a car with head phones on and the head phones melted to her head. Sound at all familiar?
