Five years ago, a tongue-in-cheek, pop-rock anthem about bi-curiosity took over radio airwaves as the world was introduced to a California girl once known as Kathryn Elizabeth Hudson.

Ten number one singles, a sold out world tour and a 3D concert movie later, pop superstar Katy Perry is back at the top of the charts with her fourth studio album, “PRISM.”

Still flying high on her latest summer smash hit “Roar,” Perry reveals a brand new side of herself through the 16 glistening tracks of her latest release.

Evidently descended from her cotton candy cloud of the “Teenage Dream” era, Perry embraces a much more mature persona for this album cycle. There’s no doubt that her high profile divorce from British actor-comedian Russell Brand provided some of the motivation behind this shift in image, as well as a goldmine of songwriting material.

Prior to the creation of “PRISM,” Perry was quoted as saying she anticipated the album to be much darker in comparison to “Teenage Dream.” However, following a trip to Africa and a deep, personal reevaluation, she began to “let the light in,” a turning point and notion that ultimately inspired the title of the record itself. With this, Perry proved to herself and to skeptics that she is nothing short of resilient.

As the first single and opening track of the record, “Roar” is Perry’s anthem and testimony to the strength of this resilience. With its powerful, stomping beat and “roaring” choruses, the song’s already established success speaks for itself.

The second track, “Legendary Lovers,” follows in suit, backing up the jungle-like, tribal tone set by the former. The final track of the deluxe edition, “Choose Your Battles,” also keeps to a similar beat, as a steady call for peace between the protagonist and her adversary. “Spiritual” and “Dark Horse” take on an eerie, almost supernatural kind of vibe, although the featuring of rapper Juicy J in the latter seems almost completely out of place and unnecessary.

Not having completely abandoned all of her sweet, lovable qualities and risqué sense of humor, Perry throws her fair share of sugarcoated pop songs into the mix of “PRISM.” With the promotional release of “Walking on Air,” she channels elements of 80s pop and disco music to create a unique, catchy dance track that could blend seamlessly into an old Madonna or Whitney Houston album.

Tracks like “This Is How We Do” and “International Smile” fall perfectly into the genre of classic pop, where synthesizers and feel good rhythms trump lyrics and depth. Also under this category is “Birthday,” a tongue-in-cheek dance track with sexual undertones and the potential to become the “Last Friday Night” of this record.

Despite these fairly one-dimensional but entertaining aspects, the remainder of Perry’s album is not at all lacking in emotion.

Her vocals soar on “PRISM’s” second official single, “Unconditionally,” a power-pop ballad inspired by Perry’s newfound romance with fellow singer-songwriter John Mayer. “Love Me,” “This Moment,” “Double Rainbow” and “It Takes Two” all follow in a similar fashion, with some being noticeably more memorable than the others.

As expected, Perry addresses Brand directly in “Ghost,” a mid-tempo declaration of her moving on from the heartbreak she endured.

Finally, as a fitting end to the standard edition of the album, “By the Grace of God” serves as Perry’s autobiographical account of her transformation through the record, and a ballad that is arguably the most emotionally powerful component to “PRISM.”
