Searching for dramatic orchestral music

Audiomachine, Immediate Music, X-Ray Dog have lots of epic orchestral albums.

Carl Orff - Carmina Burana

W. A. Mozart - Requiem (Dies Irae) (Also you might like "Rex Tremendae", "Confutatis", "Lacrimosa", etc. from the same video)

W. A. Mozart - Adagio & Fugue for Strings in C Minor (Purely orchestral, no choral)

Darksiders 2 - The Crowfather or The Guardian

I personally love the stuff from Victor Vran and The Last Door!

Scan through Mafia 1 soundtrack.

Final Fantasy series has a track record for this if you're looking for video game music. The most famous example being One-Winged Angel of course

was about to say o fortuna but it's not from a video game

Thomas Bergersen - Ocean Princess (feat. Merethe Soltvedt) is one of my favourites

Try Diablo III RoS OST
If I think correctly, that should be it
