Also any dark classical music would be cool, too.
Also, check out the first movement of Mahler's 2nd symphony.
If you don't mind post-war music, then I suggest you try Penderecki. With titles like, "Threnody for the Victims of Hiroshima" how can you go wrong for "dark classical music"? Also, Penerecki's St. Lukes Passion is over the top.
