Its says that JB Mpiana would celebrate the 20th anniversary of his music-career by a week of festivities,  performing 3 days in a row at Grand Hotel de Kinshasa with a concert at Stade des Martyrs

i will ask my brother tonight

it did not happen because of the political war behind the jb werra rivalry for example the 3 days planned were all a sudden blocked for party reunions or gospel concerts out of nowhere  and jb not being somebody who hangs on to thing ended up moving on,the year after werra also got something like cancelled due to those conflicts
