Kesha

A brash and driven, Grammy-nominated pop singer and songwriter, Kesha went straight to the top of the Billboard Hot 100 in 2009 with her breakthrough recording, a feature spot on Flo Rida's "Right Round." Her own major-label debut, Animal, followed a year later and made her a bona fide star, reaching number one in the U.S. and Canada behind the international party-time hit "TiK ToK." The album spawned three more Top-Ten singles as well as the Get Sleazy Tour, her first as a headliner. A second solo number one, "We R Who We R," was included on the 2010 EP Cannibal, and she reached the Top Ten of the Billboard 200 for the third time straight with her second full-length, 2012's Warrior. A more rock-influenced effort, it found space for prior collaborator Wayne Coyne of the Flaming Lips, punk godfather Iggy Pop, and the indie pop band Fun. She had another Hot 100-topping single a year later with "Timber," a collaboration with Pitbull. After a series of legal battles with her long-time producer, Dr. Luke, that involved claims of physical and emotional abuse and business-related mistreatment, Kesha returned with her third album, Rainbow, in 2017. Its themes of self-empowerment hit number one in the U.S., Canada, and across Europe.
