Some Russian LP Album

Good friend of mine bought me some Russin LPs, as there is no English on the cover, LP itself, I have no way to understand it but one of them is the Piano Concerto No. 1 of Tchaivosky, I am pleased with the deirector's arrnagement, music recording quality and the Lp is heavy about 140gs.
I have to say there may be still a lot of good Russian Recording, but do not expect the same quality as DGG, EMI or RCA!?
