Leno4ka, thanks for your posts. I like Bulgarian Девойки and Red berries by Slavyanki from Poland.
This folk group is from Archangel oblast’ of Northern Russia. The region in which Mikhail Lomonosov was born. He is a legendary figure in Russian society.
Folk group 'Volya' from Voronezh oblast’. The leader of the group is Galina Sysoeva . She is a well known and respected folk artist. If you are interested about women’s headdress, it is called 'Soroka' traditionally worn by married women in Voronezh and Belgord oblast’. I never saw anything similar worn by women from other regions. Voronezh and Belgorod oblast’ are in central region of Russia on the border of Eastern Ukraine.
This is a well known dance in Russian folk arts called ‘Summer’
