PRISM (Acoustic Sessions)

Prism is the fourth studio album by American singer Katy Perry. It was released by Capitol Records on October 18, 2013. While the album was initially planned to be "darker" than her previous material, Prism ultimately became a prominently dance-inspired record. The singer worked with several past collaborators, while enlisting new producers and guest vocals. Much of Prism revolves around the themes of living in the present, relationships, and self-empowerment. Critical response to Prism was generally mixed; many reviewers deemed the lyrical content more mature while others considered the album to be more formulaic than her previous material.
