Singer blamed a 'really disturbing thing' for cutting her set short

Grimes has said that she will explain why she cut her set short when opening for Florence And The Machine earlier this week (June 15).

Claire Boucher walked off stage after performing ‘World Princess part II’ at Brooklyn’s Barclays Centre. Scroll below to watch footage.

Speaking before her last song, Boucher said: “We just had a really disturbing thing happen to us today, so sorry if my voice is shaking, it’s just kind of a fucked day.” She added she was having “a little trouble keeping it together.”

The singer later took to Twitter to say: “I will explain what happened at Barclays once I can safely and legally do so.”

She added: “In the meantime ‘someone from Reddit’ or fan accounts are not credible sources. Speculating about my mental health is not news. Thanks.”

Grimes went on to say that no shows would be affected by the incident and that she has a song called ‘Medieval Warfare’ on the upcoming Suicide Squad soundtrack.

This week it was announced that Grimes was one of the artists longlisted for the 2016 Polaris Music Prize.

The Weeknd, Dilly Dally, Peaches, Carly Rae Jepsen and Kaytranada also appear on the longlist for the prestigious award, which recognises the best album of the year by a Canadian artist.

A total of 40 albums have earned places on the longlist for the 2016 prize, which recognises albums released between June 1, 2015 and May 31, 2016. The 40-album longlist will be streamlined into a 10-album shortlist on July 14, with the winner being announced at a ceremony in Toronto on September 19. A Grand Jury of 11 members will decide the ultimate winner.
