First and still one of the greatest metal bands in the history of music. Originally a blues band from Birmingham, England called the Blues Earth Company or just plane Earth as they went by. Two members were kicked out of the band and they changed their name to Black Sabbath (named after an old horror movie). The original lineup included Tony Iommi, Geezer Butler, Bill Ward, and Ozzy Osbourne. After Eight amazing albums Ozzy was being an asshole, so they kicked him out the band. Good ridance too. contrare to what you believe Black sabbath was never "ozzy's band". Ozzy didnt do shit in that band. all he did was sing, he didnt write any lyrics or anything, and his voice wasnt even all that great. The next Sabbath singer to take Ozzy's place was the master of metal singing, Ronnie James Dio. He was there the albums Heaven and Hell and Mob Rules. After Dio left several other singers came in such as Ian Gillan, Ray Gillen, Glen Hughes and Tony Martin. Dio then returned for the best Black Sabbath album, Dehumanizer. Dio then left again and Ozzy returned and i believe they are writing new songs now. The have released new demos such as Pscho Man and Selling My Soul.
Black Sabbath = pioneers of metal.
