CLEAN. 2018 release, the eighth studio album by pop/R&B vocalist Christina Aguilera. Liberation is Aguilera's first album in six years, following Lotus (2012). Liberation finds her having her way with R&B and hip-hop (Kanye West produced two tracks). Christina's soulful singing dominates the proceedings, and she co-wrote a lot of this: "Accelerate," "Maria," "Liberation," "Sick of Sittin'," "Masochist" and more! The first single "Accelerate" features Ty Dolla $ign and 2 Chainz. The album's second single "Fall in Line" features Pop vocalist Demi Lovato.
