Guitarist Tony Iommi says that this is one of his favorite Black Sabbath songs. He explained in his book Iron Man: My Journey through Heaven and Hell with Black Sabbath
: "The riff of 'Sabbath Bloody Sabbath' was the benchmark for that album. It was a heavy riff, then the song went into a light bit in the middle, and then back to the riff again: the light and shade I'm always looking for. Ozzy sang very well on it, actually on all of the songs on the album. Very high!"
