Janelle Monae and Kesha deliver the Grammys' most powerful moment

Janelle Monae and Kesha took to the stage at the Grammys and brought the Time's Up movement to the front of everyone's minds with an impassioned speech and an unforgettable, emotional performance.

Monae introduced Kesha with a poignant speech about women in the music industry and the inequality, discrimination, and harassment they face.

"To those who would dare try and silence us, we offer you two words: Time's up," Monae said. "We say time's up for pay inequality, discrimination, or harassment of any kind, and the abuse of power."

Monae set the stage for a tear-jerking performance of "Praying" by Kesha, who herself alleged abuse against her mentor and producer Dr. Luke, causing a years-long hiatus of her career.

Camila Cabello, Cyndi Lauper, Julia Michaels, Andra Day, BB Rexha, and the Resistance Revival Chorus joined Kesha on stage for a powerful performance of the artist's autobiographical song about her years of struggling to re-enter the music industry on her own terms.
