Somewhere between the chilly, ice-coated electro stings of "Break the Ice" and the gritty, slap-happy bass of "Get Naked," Britney Spears' 2007 album Blackout suddenly ran cold. The chirpy, cheerful chanteuse that I knew and loved somehow found herself wedged into the confines of a dismal, frigid vocoder, battling her own inner demons. It was a cold, dark album, devoid of soul and spirit.Now don't get me wrong, the music was there-in fact, Blackout remains Britney's sonic peak. Even her latest, Circus, cannot compete with the instantaneous, ferocious quality of Blackout. However, Britney Spears was not featured on that record. She was credited, she was singing on those tracks, but there was nothing familiar to be found.

One year later, with a refreshed image and a recovered sense of hope, Circus offers Spears' fans a proper comedown from the tumultuous past four years. It's a bouncy, bubbly romp, happily hopping between killer choruses and delicate verses. With a mixture of 2003's In The Zone's exploratory pop and Britney's seemingly unapologetic camp quality, Circus is what I had assumed Blackout to be in the first place.

"Womanizer," the album's opening track, provides great promise for what is to come. It's been played to death around the country (thankfully!), and I support all the success it has amassed. However, in comparison to the other 15 tracks, "Womanizer" is mediocre. It's a teaser of a comeback, intensely devoid of the richer quality stemming from lead-off singles like "Gimme More" or ". Baby."

It is Circus' title track that serves as the album's highlight. Upon first listen, you may think that after the song's sweat-drenched anticipation crunch of a bridge, the track would stall, but no; the chugging, ringtone-ready chorus comes storming in with an awe-inspiring amount of attitude-infused energy, playing like a classic Britney stormer: "When I crack that whip, everybody gon' trip, just like a circus." Once the track breaks into its all-too-brief bridge, Britney takes to the floor. "I'm runnin' this," she proclaims across squeaks and squeals, providing for what could only be an epic dance sequence when performed live. "Circus" is absolutely instant, an unstoppable explosion of energy and sound that deserves a killer amount of promotion and attention. With any luck, it will shortly become iconic.

Then there's "If U Seek Amy." If you haven't already caught the obscure song title's ulterior meaning, try saying it three times fast. No? Try it slow. Still nothing? Give it a listen; I guarantee you'll get it eventually. The stomp-happy, horn-heavy swayer saunters in with a delicious amount of cheekiness, proving to be as much fun as the title implies. I can't thank producer Max Martin enough for this one, and more specifically, for his scribing of the chorus line, "All of the boys and all of the girls are begging to If U Seek Amy."

I know that now, compared to the impossible standards set by Britney's prior release, some fans will inevitably feel the pangs of disappointment as a result of this album's comparably tame sensibility. However, pop enthusiasts looking for a richer, more varied experience will find solace in Circus. From the pervish, wacky space vibes of "Mmm Papi," to the ultimate floor commander known as "Circus," to the sass' n' boots, glittering '80s stomp of "Leather & Lace," Circus offers a little taste of everything.

Yet, as odd as it sounds, the greatest gift of Circus is that the album remains wonderfully, humanly imperfect. Unlike the processed-to-perfection, robotic acrobatics of Blackout, the missteps and flaws pour out from Circus: Some of the songs are hardly instant or accessible ("Blur"), some feel incomplete ("Shattered Glass"), and some may even be off-putting to casual listeners ("My Baby"). Yet in this way, the experience feels legitimate, allowing a listener to find beauty within the flaws.

With a world tour in the works for early spring '09 and a scrumptious schedule of promo appearances for Britney merely weeks away, Circus has got the musical goods to keep the energy rolling for a lengthy amount of time. As a fan, I couldn't be happier with the output: Circus is Britney's return to grace, both in form and functionality. It demonstrates the sly confidence of the Britney of yesteryear in stunning dance floor stompers like "Circus," "Mannequin," and "If U Seek Amy," and the album also promises an eventual musical evolution. For "Unusual You," "Phonography" and "Blur" all offer hints at this subtle maturation; only time will tell if it will now blossom into something deeper.

Above all, Britney Spears has proven herself to be the entertainer I have always adored and will continue to love. The album is sweet, sexy, and entirely fulfilling. Perhaps the definitive album of the year, Circus delivers in its purpose: Pure, unapologetic pop unto its innermost parts.
