While Katy Perry's single "Roar" holds court at the top of the Hot 100, other tracks from her forthcoming album Prism, due Tuesday, continue to surface online. Two songs, "Unconditionally" and "Birthday," were leaked today, following her performance of the dance number "Walking on Air" on Saturday Night Live last weekend.
"Unconditionally" is a four-minute torch song in which Perry declares her love amid sparse, echoey keyboard effects and big drums in the verses, with a lush orchestra of synth for the chorus. It's one of four songs that share production credits from Dr. Luke (who has worked with Kelly Clarkson and Rihanna) and Cirkut (Britney Spears, Taylor Swift) on Prism, including "Roar," which they worked on with Max Martin. Perry will perform the song at this year's MTV Europe Music Awards on November 10th, according to USA Today.
The other track, "Birthday," comes nine days ahead of Perry's own 29th birthday. A funky R&B dance number in the tradition of Mariah or a young Whitney with classic Eighties-style horn accents and synths, the track finds Perry promising to "give you something good to celebrate." Fans will make of that what they will.
