Lady Gaga Still Working on 'Rough' Songs for 'ARTPOP,' Says Producer

Although Lady Gaga has been talking about her next album, ARTPOP, since last fall, the songs are far from finished, her friend and producer Zedd told MTV. "We've been working on it for over a year now," said Zedd, the EDM artist, who cited busy conflicting schedules for the slow progress. "There's still a lot of work left, so we're definitely gonna work on this project for the next month."

After coming up with ideas, Zedd and Gaga tweaked and worked on the tracks while touring together in Asia last year. "I did about 10 ideas, and they were all between almost finished songs up to the piano," said Zedd. "But they're still all really rough – it could be five, it could be 10, it could be anything we want."

Lady Gaga's Born This Way Ball tour continues through March 20th. No release date has been set for ARTPOP, and Gaga revealed last month that she's written around 50 tracks for the new album. She is also planning an ARTPOP documentary with photographer Terry Richardson.
