More details are emerging about Madonna’s new album. Nate “Danja” Hills and Timbaland, who co-produced Justin Timberlake’s FutureSex/LoveSounds, are co-producing some tracks on Madonna’s yet-to-be titled album and Danja tells EW.com that the pop queen’s next effort is “very up-tempo, upbeat and urban — it’s a Virginia-based sound.” Madge was joined in the studio by another influential Virginian, Pharrell Williams, but Danja emphasizes that the album’s urban edge doesn’t mean the 49-year-old star has lost her pop cred. “It’s everything rolled into one,” he says. “It’ll be a classic album.” As previously reported here, Timbaland and Timberlake will appear in the video for Madonna’s first single, “4 Minutes to Save the World.” The album is slated for an April debut. The single drops in March.
