Query: The most beautiful piece of music in the world.

Christopher Parkening is fantastic. Today there are a lot of good guitarplayers in the world, good technic, musicality and so on, but Parkening take the word music to a new dimension. It is so much more than just music.Close your eyes and relax and let the music give you harmony.Tomas from Sweden.
