Mick Jagger’s brother Chris says the Rolling Stones frontman is hard at work on a record with producer Dave Stewart in Los Angeles. The news coincides with tweets last week from

Roots drummer Questlove, who reported he was in a New York studio with Jagger, but did not specify on what they were working. Stewart has his own album, titled “The Blackbird Diaries,” coming this spring, and worked as a producer with both Stevie Nicks and Joss Stone on their upcoming albums.
