Here's a PBS documentary was mentioned on the "Video Nasties" episode of Radiodrome.
It's about the trial of rock & roll band Judas Priest & two fans who shot themselves because of subliminal messages telling them "Do It".
It's looks like "This Is Spinal Tap" & "Rock It's Your Decision" put together.
This documentary may contain some disturbing images.
But in spite of the ridiculous debates today on movie, music & video games, it's worth a watch.
