3 DVDs with great music. DVDs are a documentary, so GG speaks about music, technique of playing, plays some pieces and explains what you should know or how he feels when playing them. The third DVD is the best one. After a short introduction about GG and Goldberg Variations, GG plays all the Variations. You can hear his humming, see his excellent pianism on your very eyes. It is a valuable collection of the best music.
