Madonna is planning a foray into rock on her next album - she's lined up Pearl Jam producer BRENDAN O BRIEN to work on her new tracks.
The pop superstar is starting her 12th studio album, the follow-up to 2008's Hard Candy, and she's looking to expand her musical style for the next record.
She has tapped O'Brien, who has also worked with AC DC and Rage Against The MAChine, as well as rap/electronic producer A-Trak, best known for collaborations with artists including Lupe Fiasco and Kanye West - prompting rumours the album will also have a hip-hop edge, according to Britain's Daily Star newspaper.
The currently untitled record is due for release later this year (10).
