Would like to add that the question is lifted truly. A subject very difficult and multi-level.
However to the USSR on television and radio regularly there were remarkable concerts on form and content of national, national collectives of a song and dances of all autonomies and republics.
I personally always liked performances of Caucasians, Moldavians and the people of Yakutia and the distant east, however with Lyudmila Zykinoj's songs too was delighted, also from vokalno-instrumental skill of chorus of a name Pjatnitsky.
:gigi: yesterday only after operation listened to the archive collection of chorus of a name Pjatnitsky, neighbors were happy. Power and a range, depth and poetry!:beer:
Any senseless flow of consciousness at a topic-starter.
