Quincy Jones tells FOX News that he’s working on a Michael Jackson tribute album scheduled for release next spring. About two dozen hip-hop and R&B stars are recording Jones’ songs for the compilation, which will include a collaboration between Usher and John Mayer.

“We’re trying to set up something for Mariah Carey now,” said the legendary producer behind Jackson’s Thriller and Bad albums.

As of now, Jackson has no plans to participate in the project.
