Recordings of the score were originally issued on single-disc albums, that closely followed the theatrical release dates 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. Many of the cues are edited to create concert suites of some of the themes such as the Ringwraith theme (in "Black Rider"), the Durin theme (In "Journey in the Dark"), the Rohan theme (in "Riders of Rohan") and the Gondor theme (in "The White Tree").
