l'Esplanade de Palais du Peuple. It took place on 6 march 1999, one week after JB's performance at the same place and 4 months after the release of Force d'Intervention Rapide. The concert was their last in Kinshasa before going to London. If you watch the full VHS you can see the concert-dates that ended up by getting cancelled (Villejuif & Olympia).
They performed there to prove JB Mpiana a point, who had massive succes there with the song Omba, the public singing with JB having light candels in their hand. So the next week, Werrason came with a horse and made that they day a record-attendance of more than 120.000 people (maybe the press exaggerated, because so far I know if you perform at l'Esplanade the max is 60.000-70.000 people). The event shocked everyone and from then the polemic started of "ba pleins". It's also one of the reasons why they voted Werrason as best star of the year 1999.
from 9:24 min how Werrason came in with a horse, the images of some people not being able to breathe, the reaction of the people and an interview of Adolphe Dominguez, Bill Clinton with journalist Ilunga Mwana Bute about the event at l'Esplanade.
the rest of the concert (I regret that IGWEJUNIOR didn't upload the bonus of their rehearshal at Zamba Playa and each musician giving his reaction before the tour and a part at Village Mbetenge)
