content: I chose this DVD based on the name of the quartet. The performance was good to excellent, but I really hate the video part of production. The stage is sometimes completely dark, intentionally. Sometimes it shows only small stream of light to certain player's face. Sometimes the screen shows all the side of players,etc. I guess the producer tried to make his own stage drama based on this music.I was not able to concentrate the music itself because the screen images change through the intention of producer's mind. And also I can not follow through the composer's score by watching players playing. It was really sad that I stopped to watch this DVD as it was too much distract me to watch.
