I only reversed on it in like 2014, a mate of mine convinced me by showing me classic Sabbath shows and stuff. Basically you trade perfection for rawness, plus a sense of history. You realise all your fave old bands were like... young... when they made this music. Idk it seems to obvious but I just never thought of it that way until I saw Ozzy Osbourne looking like a new born baby singing War Pigs
