Query: I Love this DVD, A Must But for Violin Enthusiasts

I watched this DVD over a thousand times probably. This is a extraordinary video. It talks about giant violinists of the 20th centuray, which includes Mischa Elman, Jascha Heifetz, Yehudi Menuhin, Nathan Milstein, Ivry Gitlis, David Oistrakh,and many other marvelous violinists. The videos even shows the rare recordings of Eugene Ysaye. In addition, the video also expresses many beautiful violin masterpieces played by worldclass violinists. I play the violin myself and before watching this DVD, I did not know many great violinist nor violin literature. Now, I learned the ways and styles of many violinists and violin compositions.
