Howard Shore does it again, great score. Previous themes are repeated but in a fresh way. Annie Lennox does a great job on the ending song "Into the West". (Although I must admit I am an Annie Lennox fan)
Of particular note is Track 17 "The Return of the King". Viggo Mortensen (Aragorn) renders the words of Elendil in a liturgical- style chant as he receives the crown of Gondor.
"Et Earello Endorenna utilien. Sinome maruvan ar Hildinyar tenn' Ambar-metta."
"Out of the Great Sea to Middle-earth I am come. In this place will I abide, and my heirs, unto the ending of the world."
