Lol yea Black Sabbath is pretty dark and moody I'll give you that, though I was thinking they are more 1970s. Kinda post-hippy. Lol Black Sabbath actually first CD I ever got, my carnal pops bought it for me one day when I came home after listening to Ozzy the first time and asked him if he knew any Ozzy. Lol he went out right away and got me some Black Sabbath and Ozzy cds. I think he was just happy I showed an interest in the classic rock instead of rap, though I do like rap too.
Haven't actually listened to Ozzy or Black Sabbath for a long time. Lol funniest Ozzy story I know is my friend's dad Big John whom passed away recently was a huge Ozzy fan. Well one day I'm over there with some other friends, one of them is the drummer for that band Fatal Method. And we start debating Ozzy and Black Sabbath and my drummer friend says "I think Ozzy isn't that great of a vocalist, he has very weak voice."
And my friend's dad, Big John, gets all heated over it and my drummer friend says "Ozzy sucks." Lol Big John gets up and points to the door and says "get out, you're not welcome here ever again!" We thought he was joking at first but he weren't joking he insisted and my drummer friend left. Lol only time I ever seen someone literally exiled over rock n roll. Lol me and my other friends still laugh about it to this day.
