Joni Mitchell has been writing songs recently, a close collaborator reveals in the new issue of Uncut, dated April 2015 and out now.

Jean Grand-Maître, artistic director of the Alberta Ballet, mentioned Mitchell’s recent activities as he picked his favourite of her songs in our cover feature.

“I was at her birthday party in LA last year,” the choreographer, who worked with Joni on 2007’s The Fiddle And The Drum show, says, “and she’s got more energy than ever. Her mind never stops, it’s a locomotive of thinking and feeling.

“I think there’s always a chance of new music. She was writing a few months ago – but there was the event at the Hammer Museum in LA, so I think she put that on hold to finish the Love Has Many Faces boxset. The ideas are always there.”

Mitchell’s last studio album was 2007’s Shine, released on Starbucks’ Hear Music label.

Robert Plant, Pink Floyd, Radiohead, Graham Nash, REM, Laura Marling, Roger McGuinn, Elbow and more also pick their favourite songs by Joni Mitchell in our countdown of her greatest tracks, in the new Uncut, which is out now.
