104 - Black Sabbath Sabbath Bloody Sabbath 1973

"Sabbath Bloody Sabbath" is the fifth studio album by the British hard rock/heavy metal band Black Sabbath, released in 1973. Sabbath expanded upon their slow, crunching style of music and added synthesizers and orchestral arrangements.
After the recording of their previous album, Black Sabbath, Vol. 4, the band hit a dry spell and could not come up with any songs for their new album. After locking themselves away to focus and come up with new ideas, guitarist Tony Iommi stumbled upon the riff to the title track, which has been called "the riff that saved Black Sabbath." After this song was completed, the others flowed freely.
