This comes from US industry website HitsDailyDouble, so if it's wrong, it's their fault. The Sanctuary Group have reportedly fired three of their US music managers - Tony Davis, Troy Carter and Jay Erving - who between them manage the likes of Kelis, Fat Joe and D-12. A fourth, Max Gouse, has apparently been made redundant as part of the struggling music companies restructuring, while Mathew 'father of Beyonce' Knowles, whose management company was acquired by Sanctuary back in 2003, is apparently in talks about the future of his relationship with the group.
Sanctuary boss Andy Taylor is, of course, busy restructuring the music company after a difficult year financially, though, it isn't clear if all of these management departures are related to that restructure. There is reason to believe, however, that some of the departures, at least, are acrimonious. An email circulated around certain industry types on Friday from someone called Jill Thompson, who claimed to represent all five Sanctuary managers, read thus: "This past Friday, Sanctuary Group terminated the contracts of all of their African American managers for cause. What's the cause? Sanctuary's attorneys had no answers. The managers, Tony Davis, Troy Carter, Julius Erving, Max Gouse and Mathew Knowles have retained famed litigator Larry Stein to launch a $100 million dollar lawsuit against the company". That email is seemingly wrong regarding Gouse and Knowles, though Hits Daily Double says it has confirmed that Stein is in deed representing the other three in their dispute with Sanctuary.
I am guessing http://www.hitsdailydouble.com will keep running with this one as and when any more news materialises.
