Elgar's Enigma variations just fucking does it. Especially "Nimrod". Howard shores "The Lord of the Rings" works got me a ticket for running a red light.
Last, but not least ANY of Bach's Organ Works. My fav being his Toccata & Fugue In D Minor, BWV 565. He has to be the greatest organist to ever live.
I'm also such a great fan of choral works, considering that I have a choral voice.
I have plenty of works that I consider to be great, but my all time being "Song For Athene" by Tavener. Look it up on youtube since I forgot how to embed youtube videos into my post.
