A real document! A four-track CD. Not a simple one like everything else. A four-videoclip CD! In order of appearance: "Paranoid", "Black Sabbath", "Iron Man", "Blue Suede Shoes". Each one a classic, even the cover of "Blue Suede Shoes". Unfortunately, the picture and the sound are not the best that I've come across. This always comes with "illegal" or "semi-illegal" recordings. Fans of the Greatest Band should buy it now. As for the rest, only the owners of computers should look for it. How can I grade this? Even though I try to be objective...
