4. Sabbath Bloody Sabbath (1973): Not only is the album itself amazing, but everything peripherally attached to it is also amazing, such as the cover art by artist Drew Struzan (who also did film posters for blockbuster films like Star Wars and Indiana Jones). The album also featured guest synthesizer/piano work from Rick Wakeman. But the most fascinating part of the production itself might be that when the band found writing in Los Angeles to be too difficult, they decided to write the album in the dungeon of Clearwell Castle in Gloucestershire, England. While the album does feature a couple of questionable songs (notably, “Who Are You?” penned by Ozzy, and Iommi’s appropriately titled guitar ballad “Fluff”), the album’s strongest track is the eponymous “Sabbath Bloody Sabbath.”
