“It’s so important when you are abroad, to still have this community, to feel the spirit, to have this identity,” said Ms Grebeniuk.
The concert featured performances from from acclaimed Ukrainian artist Eka i Bandura and the Svitlo choir.
“We as a nation love singing,” continued Ms Grebeniuk. “Our songs are about everything – love, pain, everything.”
