Biggest Weekend: Rita Ora pays tribute to Avicii
Rita Ora paid an emotional tribute to dance producer Avicii as she opened up the third day of the BBC's Biggest Weekend festival in Swansea.
Avicii's name flashed up on the video screens as Ora sang their collaboration Lonely Together - the final single the DJ released before his death in April.
"Thank you for singing that with me," she told the crowd as the song ended.
"It's always hard for me to sing that, so thank you so much for singing along."
Ora has previously said described Avicii as "a really good friend" who "changed my life".
The Swedish musician, born Tim Bergling, died last month at the age of 28.
A statement released by his family seemed to suggest the cause of death was suicide.
Best known for the international hits Wake Me Up and Levels, he had recently retired from touring, saying the lifestyle was taking a toll on his health.
After he was found dead in Oman, DJ Pete Tong suggested it was "time to establish a support group" for musicians who found themselves overwhelmed.
Ora is not alone in paying tribute to Avicii.
Calvin Harris said he was "devastated" and called the star "a beautiful soul" while Imagine Dragons said "the world was a happier and fuller place with his presence".
Avicii's family announced last week that his funeral would be held privately "in the presence of the people who were closest to Tim".
