Charismatic Valery Gergiev conducts the Mariinsky Orchestra in the Tchaikovsky's 4th, 5th and 6th symphony at the Salle Pleyel, Paris. Naturally, the orchestra could play it in their sleep,for this playing of the symphonies is Russian to the core and you can see they love these symphonies. The energy generated in the 4th symphony is a wonder to behold. The conclusion reminds me of Mravinsky's rendition of this symphony. They play the lyrical parts of the 5th with feeling. The 6th's last movement is played with emotion. I throughly recommend these symphonies conducted by a master of his craft, with a easy to read beat.Forget the criticism of the filming of this bluray,some people are very fussy,or they have a dodgy bluray machine. I found the filming excellent.surround sound 5.O HD master. stereo 2.O 1080i HD 16.9.
