According to a lawsuit filed by two of Muni Long’s managers, the singer owes them over $600,000 for “unpaid commissions.” In a federal courtroom on Thursday (Oct.23), Long’s former managers, Chaka Zulu and Jeff Dixon, claimed the Grammy Award-winning R&B singer is in “breach of contract.” Zulu and Dixion are the founders of Ebony Son Entertainment, an Atlanta-based management company. The duo is mostly known for their previous work, managing Ludacris and eventually starting the record label, Disturbing Tha Peace in 1998.
