Three of the pieces derive from the composer's cycles of works based on the mythology of J. R. R. Tolkien, and form appendices to his epic scenes from The Silmarillion and his musical chapters from The Lord of the Rings (to be released in a complete recording by Prima Facie later in 2025). Piano Rondo: "Akallabeth" depicts the story of the Second Age Kingdom of Men and it's downfall; the Wedding March from "The Fall of Gondolin" is an arrangement for piano of a section of that work; and Piano Episode: "The Passing of Arwen" forms an epilogue to The Lord of the Rings, drawing on material from the cycle and telling of the tragic conclusion of the tale of Aragorn and Arwen.
