Led Zeppelin IV by Led Zeppelin

"Something else, though, happened with Led Zeppelin IV. There was an invocation of history and horror (and a bit of Lord of the Rings) in "The Battle of Evermore," and the suggestion of a shared mission of spiritual hope in "Stairway to Heaven." Just as important, though, was what was not on the album: any discernible title. The four runic symbols that function as both the record's real name and as representations of the personalities in the band had no clear meaning, but that made them more evocative, more a possibility than a meaning. (Page designed his own zoso-looking symbol and would never explain its significance—he told Plant only, but Plant forgot what it meant—while Bonham's pattern of intersecting circles resembled the logo of a beer he liked.)"
