Top Frisson One used to be an atalaku from a band in Brazzaville, then he came to France and joined Jeunes Premiers. He sung on their album Premillenium and had even a song on that album. That's why he's so attached to Congolese music.
Don't forget that before 2012 you had a quota on French media (television, radio, etc.) for black artists and even for those who were making Zouk-music. If that quota didn't exist in 2003, then Coupe Decale-artists like Douk Saga, DJ Jacob, Molare, Anofela would have colonized France and Belgium like Naza, Keblack are doing today.
Kaysha's career failed ? That guy sold millions albums around the world more than Naza, Keblack and Vegedream together. It's just that you can't be for 20 years non stop on the top. Since 2005 he concentrates more on his musiclabel Sushiraw and managing young artists. He's the person who discovered Lynnsha. The same Lynnsha released her third album under his label.
