During an interview with NJ's The Star Ledger, concert promoter Patrick Allocco, who is still being held in Angola with his son, said that Nas returned $200,000 of his $300,000 payment to perform but won't fork over the rest.

"He is supposed to send another $100,000, but now he is reneging," Allocco said. Allocco and his son are in an Angolan hotel hoping to resolve this "nightmare."
