haunting/dark classical


new to classical, I really like Samuel Barber's Adagio for Strings, Op 11. I am looking for other music with the same dark/haunting sound. Suggestions?

Try Danny Elfman much of his work, Prokofiev Romeo & Juliette, Mahler much of his work, Mozart Requiem, Don Giovanni, Wagner much of his work, Verdi Chorus of Hebrew Slaves ...too works to many to list here
Check out Hovhaness-Symphony No. 2 ("Mysterious Mountain") and Gorecki-Symphony No. 3. Both are dark and Hovhaness in particular reminds me of Vaughan Williams. Enjoy the music.
Sall4
A little off the beaten path and more recent than those already mentioned; Silvestrov(sp?) from the Ukraine. Dark and brooding but not as "thick" as above mentioned romantics. I believe there are at least 3-4 CDs available.
Olivier Messiaen
"Quartet For The End Of Time"

Its inspiration, alone, meets your interest. The music even more.
