The sound of the lead-guitar was also bad when they performed in the Estadio da Cidadela in Luanda back in 2000.

I have already been to a concert  . Soundcheck was made by Ali Mbonda Mimiche and Coreen ... 20 min before the entry of Heritier and his colleagues (Miel , Taddet , Cappucino , Oliveira , Jr marot )

How was it possible that the lead-guitar was often off or half ?

I think for this concert, there was a Mixing issue. No sure if the people who attended the concert heard what we all are hearing for the concert.

You went late.

I was not there but videos of sound test and final practice showed that the test was done earlier.

Most Masion Mere concerts often had poor sound..it seems the promoters didn't have a budget to hire professional sound engineers, they had to rely on flamme, ali mbonda, etc  who in most cases don't have the know how. Werrason was always late to everything rehearsals, sound check etc.

This is the only concert that had a decent sound
 

You can hire a proffessional sound engineer but everything rests with the band when you do a sound check.You then set up the system the way you want.At a live show the sound is mostly the decision of the band.
