"Station to Station" is often cited as a transitional album in Bowie's career. Nicholas Pegg, author of "The Complete David Bowie", called it a "precise halfway point on the journey from "Young Americans" to "Low"", while for Roy Carr and Charles Shaar Murray, it "effectively divides the '70s for David Bowie. It ties off the era of Ziggy Stardust and plastic soul, and introduces the first taste of the new music that was to follow with "Low"." In terms of Bowie's own output, "Station to Station"'s Euro-centric flavour had its musical antecedents in tracks like "Aladdin Sane (1913-1938-197?)" and "Time" (1973), while its funk and disco elements were a development of the soul sound of "Young Americans" (1975). More recently Bowie had begun to soak up the influence of krautrock and electronic music by bands like Neu! and Kraftwerk. Thematically the album revisited concepts dealt with in songs such as "The Supermen" from "The Man Who Sold the World" (1970) and "Quicksand" from "Hunky Dory" (1971): Nietzsche's 'Overman', the occultism of Aleister Crowley, Nazi fascination with Grail mythology, and the Kabbalah. Pegg considered the album's theme to be a clash of "occultism and Christianity".
