I listened to Howard Shore’s excellent soundtrack for the LOTR films while I read The Silmarillion. I’m usually reading on the train and so need to drown out the ambient noise. Given how long it took me to read the book, I’ve probably ended up listening to Shore’s score twenty or thirty times.
Every time, when Emiliana Torrini’s rendition of “Gollum’s Song” comes on, I have to stop reading and just listen. It may be one of my favorite pieces of film music.
Billy Boyd’s performance in “The Steward of Gondor” is a close second, though.
