It is in the neofolk genre and addresses themes of spiritual decay, with influence from writers such as Rudyard Kipling, Friedrich Nietzsche and George Orwell.

The press release for The Lone Furrow says the album is targeted against the "despiritualized modern age" and promotes a cultural heritage present in Hermann Hesse, Friedrich Nietzsche, Tacitus, George Orwell, Ovid, the Prose Edda, W. B. Yeats and Charles Baudelaire.

[2] Marco De Baptistis of Ondarock [it] and Wolfsbrunn wrote that The Lone Furrow sees Rome return to its musical roots of "martial" neofolk.

[1][2] De Baptistis said "On Albion's Plan" is an exception, because of its similarities to the folk music of The Dublin Session (2019), but otherwise, The Lone Furrow is reminiscent of Rome's first three albums, released by Cold Meat Industry.

[1] Wolfsbrunn wrote that The Lone Furrow differs musically from Rome's two previous albums, The Dublin Session and Le Ceneri di Heliodoro (2019), but it retains the latter's political discourse about progress and globalisation, and has similar provocative elements.

[1] Oliviër Bernard of Obsküre [fr] described a dramaturgy throughout the album which combines the motifs of spiritual decay and rage with the belief that beauty can save humanity.

[7] Claudia Zinn-Zinnenburg of Orkus wrote that the opening track's questioning of modern society runs as a red thread, allowing the album to be both critical and open-minded.

[8] Lawson praised The Lone Furrow's musical formula of drums, synthesizers, acoustic instruments, reverb and Reuter's baritone voice, and said the latter's songwriting abilities have matured, highlighting "Tyriat Sig Tyrias" and "Ächtung, Baby!"
