"Oka Bisso"
Summer 1983 to be specific, following the release of the incredibly popular Muvaro, which presented Atalakou chants such as Fiona-Fiona, Zekete, and Fongi. Zaiko at the time was the first band to have singers and instrumentalists dance during Sebene, which greatly increased crowd interaction. The only issue was they didn't have choreography at that time and it really shows.
Then there was Etape, a composition by Max Mongali, which I believe was the ballad of the year, if I recall correctly.
The then young guitar wizard, Beniko Popolipo played with such calmness.
The first exposition of the Atalakou, with Bébé and Nono Atalakou and their shakers was in summer 1982, during the time of the World Cup on National television. Initially when Zaiko introduced Atalakou, meaning "look at me", the audiences couldn't quite grasp what was going on. What was initially a controversial addition became the cornerstone and what brought Congolese music to new heights, fueling African dance music through the 80s and 90s.
