Paranoid
The riffs on Paranoid are famous enough to seem obvious, but Black Sabbath make them feel remarkably unsettled. Tony Iommi's guitar figures leave spaces that Geezer Butler and Bill Ward fill with movement. Ozzy Osbourne's plain, anxious voice gives that restless music a human centre.
War Pigs is the best demonstration. The opening has enormous weight, yet the song keeps changing its balance. Ward's fills interrupt any comfortable march, while Butler often sounds like he is answering the guitar rather than simply supporting it. The antiwar anger becomes more convincing because the arrangement has its own argument going on.
The title track cuts everything down to a brief, urgent burst. Its directness is a strength. Osbourne's vocal sounds trapped inside the rhythm, and the guitar solo offers a quick flash of release before the main idea returns. There is little distance between the song's worry and its musical shape.
Planet Caravan opens a different space, with a soft vocal, light percussion and an unusually gentle guitar sound. Its quietness makes the entrance of Iron Man more imposing. That song's central riff is only the beginning: the changes in pace give the story a sense of development that a single heavy figure could not provide.
The second half is equally important to the record's character. Electric Funeral has a sickly, unstable feeling, while Hand Of Doom moves between exposed quiet passages and much harder attacks. These songs can sound crude beside more polished metal, but the lack of polish makes their unease more immediate.
The brief instrumental Rat Salad is less substantial as a composition, though Ward's playing gives it a clear purpose. Fairies Wear Boots then closes with a loose, swinging confidence. Across the album, Sabbath let heaviness breathe and change shape. The songs feel threatening because they contain uncertainty, movement and personality, with much more happening beneath the famous riffs than their familiarity might suggest.
