Ethereal classical music

[JW1]

Hi, I like the work The Unanswered Question from Charles Ives very much (see for instance http://www.youtube.com/watch?v=trkFgIMC-Ks). Does anyone know classical music similar to this work?

Perhaps groups such as Midnight Syndicate or Nox Arcana will suite to your taste?

For a truly strange but haunting piece of true classical music try Tavener's "Celtic Requiem" here is just a short clip from it
