Katy Perry Halfway Done With 'Schizophrenic' New Album

Among the new songs is a track called 'Double Rainbow.'

Katy Perry doesn't do anything half-way. When she tours, she tours big and when she records an album, she's all the way in. And, from the sounds of it, the singer's follow-up to 2010's Teenage Dream is an intense, emotional affair.

"When I put myself on a timeline, when I tell the record company when I want to release the album, that's when the race starts," she said on Thursday at ASCAP's I Create Music Expo, according to Billboard. "That's when I put pressure on myself."

Perry said she's already halfway through what she described at the event as a "schizophrenic" album. Dream spun off five Hot 100 #1 singles,
 and so, not wanting to rock the boat, Perry is working with a number of the same songwriters, including Max Martin, Dr. Luke, Greg Wells and Bonnie McKee.

"Max and Luke push me the most. As a team we have certain strengths," she said. "With Max, it's melody choices, Luke is production and I'm topline and melody." Perry said she's also been writing with Australian singer/songwriter Sia (Christina Aguilera, Madonna), who co-write and sang the David Guetta hit "Titanium."

"She makes me laugh more than any human," Perry said of Sia. "I can't do vocals because I fry my voice from laughing."

Though Perry was light on details about songs, she did reveal one whimsical title that may make it onto the album. She described a recent session where she came into the studio and presented a melody and verse to producer Greg Kurstin and McKee. "She came in from a yoga class and said, 'I want to write a song called 'Double Rainbow,'" said Perry of McKee, who co-wrote "Part of Me" and "Wide Awake" and has penned hits for Ke$ha and Britney Spears. "So we have a song called 'Double Rainbow.'"

On Thursday, she gave another tantalizing hint about the album with a playful tweet that read, "You know the 90's are back when you're voluntarily putting record scratches in your songs a la Portishead's Dummy."
