Kesha puts a difficult couple years behind her and lets the music do the talking on the new, 14-track set which features a rage of guest artists from Eagles of Death Metal to Dolly Partonand the Dap-Kings Horns.
Ben Folds, Ricky Reed and others lend their production talents to the comeback set, which "marks a new beginning for Kesha, one based around inner strength and musical exploration," reads a message accompanying the new release.
The singer will support her new release with a six-week Rainbow Tour of North America kicking off from September, her first solo outing since 2013's Warrior Tour.
