The most valuable asset of Belorussia was its legendary soviet times folk or pop (not sure of the appropriate term) group - Pesniary. This is one of their songs of that era in a not so perfect sound quality, by today’s standards, but nonetheless so dear to many Russians and Byelorussians who remember the time.

They say there was an American tour they made in the 70s, which was a great success. It’s hard to say was it mainly Russian emigrants or general American audience that liked the band and was there any success at all and not just a propaganda bubble. Did anyone by any chance hear of the band then or any time later on? And, btw, about the song, what would you say of it, honestly though? Keep in mind, it’s more than 30 years old and it is in Byelorussian, something about love. :)
