After reading this text I have found out that they all have in common it's that fact that their concerts take place in Belarus. Because all these singers, such as: Troitza, BeZ Bilata, Seryoga, Alyona Lanskaya and the National Concert Orchestra — they are connected with Belarus. Seryogas songs are listened while driving in the car in Belarus, Alyona has won the Slavianski Bazaar Contest, Orchestra was founded by the Belorussians, BeZ Bileta play pop music based on Belorussian folk and Troitsa have already recorded six albums in studios in Belarus.
The difference between them is that they perform different styles of the song music. Troitsa play a wide range of instruments,
BeZ Bilata and Alyona Lanskaya are Belarusian pop singers, the National Concert Orchestra play from old Belorussian music to jazz and pop and Seryoga performs hip hop and rap.
