Pink Floyd is releasing its first new music in almost three decades to raise money for the people of Ukraine, the band has announced.
"Hey Hey Rise Up" features Pink Floyd members David Gilmour and Nick Mason, with vocals from Ukrainian singer Andriy Khlyvnyuk of the band BoomBox. Roger Waters, who left the band in the 1980s, is not involved.
The track features Khlyvnyuk singing a patriotic Ukrainian song from a clip he recorded in front of Kyiv's St Sophia Cathedral and posted on social media.
Gilmour, who performed with BoomBox in London in 2015, said the video was "a powerful moment that made me want to put it to music".
After Russia's invasion, Khlyvnyuk cut short a tour of the US to return to Ukraine and join a territorial defence unit.
