ambiguous, as it might be referring to the evident resemblance of The Lord of the Rings to Wagner's operas, or "obliquely" to the question of race in Middle-earth, whether depicted by Tolkien or Jackson. Donnelly cites Mark Brownrigg as stating that Shore's score "marks a homology between [Wagner's] nibelungen and the Orcs", commenting that the parallel makes Shore's use of Wagner-style leitmotifs "apt". He is less certain of the appropriateness of the use of sounds from the Maghreb and the Arab world more generally for themes representing evil. These include the evil wizard Saruman's Isengard and the Dark Lord Sauron's Mordor (which like the equally evil Ring theme uses the rhaita), something that Donnelly calls "a fairly problematic use of musical representation". Donnelly, noting that Shore treated the music as a whole, unlike in most films, quotes Shore's account of his intention: "The concept is opera and it's the reverse of writing an opera and then having it staged. What I'm trying to do is [to] have the same feeling so that when you watch the film, it feels seamless, it's almost like the film was created to music." Donnelly adds that at moments like the Battle of Helm's Deep, the fighting is "evident in the interplay of musical themes" as the Elvish archers' Lothlórien theme battles the Orcs' Isengard theme. Recordings Original soundtracks Recordings of the score were originally issued on single-disc albums, named The Fellowship of the Ring, The Two Towers, and The Return of the King, that closely followed the cinematic releases of the films, or presented earlier versions recorded during the film's editing. The music on the disc was arranged as a concert-piece while also keeping reasonably with the plot progression of the film. The Complete Recordings Starting in 2005, a year after the extended release of The Return of the King, Reprise Records released one multi-disc set for each part of the trilogy. These annually published collections, titled The Complete Recordings, contain the entire score for the extended versions of the films on CD, along with an additional DVD-Audio disc that offers 2.0 stereo and 5.1 surround mixes of the soundtrack, and liner notes by Doug Adams. They were re-released in 2018 by Rhino Entertainment. The Rarities Archives The 2010 book by Doug Adams, The Music of the Lord of the Rings Films, contains a companion CD, The Rarities Archives, of alternate versions and otherwise
