Kesha’s legal case against the producer Dr. Luke, accusing him of physical, emotional, and sexual abuse, has become an overarching narrative in the singer’s career since it was opened in 2013. She only brought out one single for the entire duration of the case, but with her return to music in 2017 – with the release of Rainbow, her third studio album – she adopted a firm, feminist stance against abuse and in support of its survivors. In support of #MeToo, she performed the lead single from the album, “Praying”, at the Grammys back in January.

Now, a year after Rainbow’s release, Kesha is to put out a documentary about the making of the album and her struggles so far. Rainbow – The Film will be directed by Kesha herself, alongside her brother, Lagan Sebert, and Kevin Hayden. To tell the singer’s story, it will combine true-to-life documentary and more psychedelic, impressionistic clips.

All of this can be seen in a new trailer, which begins with a voiceover from Kesha – “Sometimes things feel like they’re too much to handle…” – that gives a sense of the documentary’s themes. “Depression, anxiety and mental illness are things we all need to talk about more, and there is no shame in asking for help,” she adds in a statement. “Making the decision to work on yourself is the bravest thing you can do.”

Rainbow - The Film will be released on Apple Music, August 10
