Annie Lennox is plotting a comeback after teaming up with Alanis Morissette's songwriter-producer GLEN BALLARD on her "most intense" album. The former Eurythmics star and Ballard are working on Lennox's first album in four years. Grammy Award winner Ballard tells, "It's a very intense record. It's very personal to her. We spent a lot of time making sure the music was the way she wanted it." Ballard's slate is very busy - he's also producing RENT star IDINA MENZEL's debut album.
