I don't believe that he will fill the stadium even if it is for free. He doens't also have a big fanbase like most musicians in this era. Times have changed, people are not interested in music anymore like it used to be in the 2000s. JB Mpiana and Werrason both didn't fill 100% of the capacity when they performed there for the first time in 1999. I think that it would be better for Heritier to start with Stade Tata Raphael instead of Stade des Martyrs, which is also not easy to fill. Even derbies like AS Vita vs CS Imana have difficulties to see both Stade Tata Raphael and Stade des Martyrs being filled. Heritier has to come with a strategy to perform like 3 months abroad in African countries and then come back, maybe that it will lure more music-fans.
Fally always likes to be first in everything so I don't see him perform right after Heritier. I think that he will wait 2/3 years more or quickly come with a date before him.
About Heritier annoucing his concert at Stade des Martyrs 6 months before the event. I've never seen it. Back in the days they would just put a date 3/2 weeks before the event and prepare the event from then.
