Kesha's documentary cover art. Picture: supplied

This Friday marks one year since Kesha made a comeback and released the Grammy-nominated album, Rainbow. To celebrate, Kesha will be taking fans through a journey through a documentary called Rainbow: The Film. It will be exclusively available on Apple Music on August 10.

For this doccie, Kesha sits in the director’s chair. But she also shares it with Lagan Sebert, who is her brother, and Kevin Hayden. 

The chart-topping singer has gone through a lot in the last few years and Rainbow is meant to show her coming back stronger and better.

Creativity seems to have got her to this point. Kesha said: “Making 'Rainbow' the album was such a therapeutic process and given the opportunity to turn it into a three-dimensional piece of art has helped me find even deeper healing and catharsis."

She continued: "I hope this film inspires others to never give up even if you feel full of hurt or lost because after the storm comes a rainbow. Depression, anxiety and mental illness are things we all need to talk about more, and there is no shame in asking for help. 

"Making the decision to work on yourself is the bravest thing you can do.  I hope this film helps bring light and love to everyone."
