I have to say, this is one of the best things I have discovered in years...
Some time ago I read something about David Arkenstone in a prog/newage oriented forum, and bought the cd "Caravan of Light". Since then I have already got five other cd's - "The Celtic Book of Days", "Citizen of the World", "Another Star in the Sky", "Spirit Wind" and "In the Wake of the Wind" -, and the idea is to get more, because I am really amazed by the music of this guy.
This is the kind of new age I always dreamed about: high quality quiet music with clear progressive elements throughout.
