From pop and rock to rap, metal and electronic: popular music in Ukraine has been a part of the national awakening since 2014. Now, once again, Ukrainian musical culture is under attack from Russia. But the music goes on, despite all odds, with artists contributing in different ways to the war effort.   It is 22 February 2022 and the Mariupol Theatre is full. Andriy Khlyvnyuk is on stage with his band BoomBox. Popular throughout Ukraine for two decades, the band’s songs fit every occasion: whether you are falling in love or breaking up, laughing or crying, in a stadium or at the front. But this evening the atmosphere isn’t festive. In just over 24 hours Russia will invade Ukraine.
