One of the darkest riffs of all time.   So mood inducing.

Imagine what the parents were thinking hearing this come out of their kids room in 1970.

That album cover still creeps me out.

The birth of Metal. I hope this means you are going to do their whole discography like you did with Zeppelin.

Just imagine, this dark album was released on Friday February 13th 1970!

53 years later, still one of the heaviest riffs ever written. pure fucking metal.

The birth of heavy metal.

One of the best Halloween playlist songs of all time.

Toni iommi best and heaviest riffs in rock period

Black Sabbath is top 3 all time

So, I was around 12 or 13 and I went over to my friends house and we hung out. We turned the lights down low and listened to this album. Then I had to walk home, alone in the dark with this song ringing in my ears. Never been so scared in my life.

Band name came from an old Boris Karloff horror movie. Killer debut

Imagine being so stoned you can't move...in a room lit only by black lights...with either a great set of headphones or great speakers...just grooving with friends.  Awwwwww...the 70s.

Steve Vai once told Ozzy that this album is out of tune. Ozzy responded with “Rock music is not supposed to sound perfect. If you want to hear perfect, go and watch a fucking symphony orchestra.”

No genre was ever created so completely, so quickly. This is decades worth of musical of evolution.

The sort of creativity you can only find down at the crossroads...

I was 15, I couldn't believe what I was hearing. This song changed music.

I can imagine the faces of the people who dropped the needle on this track in 1970... Minds blown and freaked out. Dayum!

This is where it all started !!! Heavy riffs inspired by grainy grimy Horror movies from Hammer, Amicus and American International !! The movie named " Black Sabbath " starred Boris Karloff and is pretty cool too.

This song was terrifying. Even the guitar solo sounds panicked and scared. They were practicing across from a movie theater and were watching this long line of people going to see a horror film, and thought what if we made a horror film but with music instead of film. People love to get scared. They pretty much created a whole genre of music with this song.

Radio stations wouldnt play them for this reason. But they got so popular they couldnt refuse.
