Lux Aeterna?

Can someone please suggest some music that is similar to Lux Aeterna? What i like about it is that it is haunting and sinister. I like that it is stringed instraments. I'm not that big of a fan of a many instrament orchestra. One of the few exceptions to this is O' Fortuna. I love the violin in the song. Now that you know what i like about the song hopefully it will flush out some suggestions.
