Black Sabbath in 1970, photo by Warner Brothers Records
On the sleeve: a grainy picture of a woman dressed in black. A stagnant pond. A creepy looking mill house.
And two words. Black Sabbath.
On the record: Rain. Thunder. A tolling bell. Those three notes. That voice.
And just like that, in February of 1970 – appropriately enough on the 13th – the face of music was changed forever.
