Query: The Grieg bible

Got hold of a copy of the book at the Edvard Grieg Museum in Norway. The book gives a full introduction to Grieg's life in a chronological as well as a thematical order. It is possible to read for nonmusicians, but with some knowledge of music, the book is simply excellent. The list of works, both with opusnumber and those without, is valuable to everybody who wants to have an overlook of his works.
