Wagner's Ring is an impossible work. It requires sets that defy all practicality, singers who can manage to both act and sing as well as being heard over a vast orchestra as well as players and a conductor able to make what can easily become a sagging and protracted mess into a riveting drama. I am no Wagner expert but this is a great introduction to the Ring. There are many positives: brilliant filming in Blu-ray, dramatic sets and lighting, no attempt to impose some stupid interpretation on the text and some very fine singing (especially Bryn Terfel)and playing. The recording is excellent and the quality extends even to the details; the subtitles are carefully located on the screen. No, it isn't perfect but here perfection isn't possible. If you want to get to know what is one of the greatest (if flawed) artistic creations of Western Civilisation this is the best way in. It is not even particularly expensive!
