This is one heavy album. And the opener Requiem is the albums heaviest song. The album is carried by the greatness of Requiem. Requiem is the perfect distillation of classic Black Sabbath through the filter of 1980s Punk/post punk in GB. Both reminiscent of the past as well as predicting the Goth and Industrial styles to come. There are other good songs on Killing Joke, But its Requiem that makes this album a 4.5
