Is it true that some rich businessmen(JB donors) who where not happy with Mpela's departure and a businessmen who had a personal conflict with mpela (the rumours where that Mpela slept with his wife) did everything to let this album flop(buying every cd so that no one can buy one, withcraft etc.)?

  Interesting rumours.

Not many but one yes its true but its not important to say who exactly but indeed a lot of intifada cds were burned or thrown into seas and ofcourse  spiritually attacked,jb himself had other things to care about lol,i still never believe when i hear that jb and amida agreed to let her go so they can become richer when i look how completely down jb looked except some good patches until she returned in 2009
it was even to the point that he tried to get alain mpela kidnapped and beaten,its one of the reasons why afande was much abroad from after intifada,lol the mpela/bongongo's and all the problems they have because of women so far only  ronsard is "clean"
also most of bcbg's donors were ready to pay him to come back because they said both him and jb still needed each other

(buying every cd so that no one can buy one, withcraft etc.)?

Man where would Congolese music be without these constant childish behaviors by the musicans and donors; they seem to go hand in hand.

the last case of that type was the three lots of memoire ya nzambe which were thrown away...
