Los Angeles: Singer Lady Gaga's producer RedOne says her new album is a mixture of "classic" and "futuristic" sounds. The Moroccan-Swedish producer -- who has worked with Gaga since her 2008 debut album "The Fame" -- has revealed the "Born this way" hitmaker has completed a total of eight tracks for her eagerly-anticipated fourth studio album, and that it retains her trademark sound, reports people.com. "It's a mixture of classic music and futuristic too. I didn't want to go too far from what she is. We kept it (similar to) what Gaga is what she's done all these years. It's special," RedOne -- whose real name is Nadir Khayat -- said. "All I know is that we did eight great songs so far, and I think we have incredible songs," he added.
