Russian punk band Pornofilmy and Ukrainian pop-rockers Nervy are performing together on a charity tour entitled "Stand with Ukraine".
They say profits from the concerts, the latest of which took place in the Polish city of Gdansk on Wednesday, will be donated to organizations helping war-affected Ukrainians and used for the purchase of medical equipment.
The tour, which also features Russian rapper Face, was initiated by Nervy frontman Zhenya Milkovskyi, who was born in Pokrovsk, in Ukraine's Donetsk region, and had been living in Moscow since 2014 after signing with a Russian label.
