Query: Stop insulting Russian music OR let the Russians conduct!

Valeriy Gergiyev, the most dull, most uninteresting and most non-Russian conductor in the world, is doing his best to make all foreigners think that russian music should be performed like a mixture of Rossini and Wagner. The "Tsar's bride", on of the greatest operas ever written here sounds like a cheap provincial recording. The worst singers are Olga Borodina and Marina Shaguch. Listening to them is like comitting suicide. Choose one of the three Bolshoi versions and enjoi real RUSSIANS, singing a real RUSSIAN opera. From Moscow, the greates opera city in the world,with love, V. M. K.
