Quincy Jones’ breach of contract claims involving posthumous Michael Jackson releases will proceed to trial next month, after a judge on Wednesday denied a motion for summary judgment.

The fight began in 2013 when Jones sued Sony Entertainment and MJJ Productions, a song company controlled by the King of Pop’s estate, claiming master recordings he produced were wrongfully edited and remixed to deprive him of backend profit participation. The works at issue including the This Is It film and soundtrack album and the 25th anniversary edition of Bad.
