This was the singer's first public appearance on stage since her case against Dr. Luke's Kemosabe Records was dismissed.
Kesha claimed that the producer had sexually assaulted her over the years, which he has strongly denied.
She has received support from a number of other celebrities, including Lady Gaga, Adele and Taylor Swift as well as fans with the slogan #FreeKesha.
The lyrics from 'True Colours' have been interpreted to reflect her personal situation.
