From wiki:
Trio Mandili (მანდილი, “woman’s headscarf”) is a Georgian musical group which currently consists of Tatuli Mgeladze (თათული მგელაძე), Tako Tsiklauri (თაკო წიკლაური), and Mariam Kurasbediani (მარიამ ქურასბედიანი).
They perform polyphonic singing accompanied by a panduri, a traditional Georgian string instrument. They became popular in Georgia when they uploaded a music video in which they perform a Georgian folk song, “Apareka“. This video, posted online, gathered over seven million views.

The girls love Ukraine, sometimes sing in Ukrainian and formed a charity to help Ukraine: Mandili Cares.
Here they are two years ago; wearing vishivankas and performing a Ukrainian classic : Pidmanula:
These fabulous girls are angels. Despite all the problems in Georgia, they devoted themselves to helping Ukraine.
