Dindo Yogo: RIP, Dindo Yogo is a legend I mean you won't get singers who can do Baritone and Tenor with such class easily Ya Yogo can do that but the manner of his singing is completely weird but yet so good, quite like a sheep example "Kopesa Te e-e-e-e-e-e-e", very fascinating, unique and bizarre but nonetheless a great singer who left his mark many singers are influenced by him most notably his children once again R.I.P.
Koffi Alibaba: If your old enough this guy is so so so weird when it comes to singing, don't get me wrong his really good but has a weird style, an extreme high voice, adventurous as ever "Eh Eh Ah Ah Haaaaaaa Ngai Eh He He Heeeee Ha Ha Haaaaaaaaaaaaaaa Ngai Eh Ehhh" Alibaba will never stop you can't literally control but like with him adds a complete different style that resembles well with other singing styles and dominates.
Didier Lacoste: Top singer, as I have more knowledge with the Wenge generation, Didier Lacoste is the first singer to completely kill the Wenge singing culture if you look at past high voiced singers for instance JB Mpiana, Manda Chante, Aimelia & Ferre Gola all have something common is that they sing in a Debaba/Papa Wemba type but Lacoste completely re-shuffled, changed and revolutionized new weird singing style a new color introduce to the generation Wenge. A completely high voice that dominates choruses and a different singing style example "Na Zelaka yo Zonga mawa Heeeeeeeeyayayaya, Werrason Azalakiiiiiiiiiiiiiiiiiiiii", listen to Chantal Switzerland, Cresois, PDG Makambo & 13 Ans. His vocal completely weird but good and unique, If singers like Gibson, Soleil Wanga, Eboa-Lotin and others came out they have Lacoste thank because if he flopped with Maison Mere not many modern leaders would trust weird singers but he opened the doors for all weird singers in the Wenge generation lost of respect Lacoste.
Soleil Wanga: Fantastic singer but yet again weird, Vocals on "Suivez Le Guide" = "Orrrrrrrdonanceeeeeeeeeeeeeeeee" and "Nga nako kende Wapiiiiiiiiiiiii", his own on Affaire D'Etat "Allo Allo, Allo, Allo, Allo, Alloweeeeeeeeeeeeeeeeeeeeeeeeeheeeeeeeeeee" and the Best "Bilan" that vocal won him revelation of the year 10/10 <the real Soleil, currently his utterly weird that I don't understand him and his just toooo weird with his singing but still quality.
Eboa-Lotin:

very good singer infact world-class but weird like the others, "Bolingo ya nga Joel photo mbetenge ndeeeeeeeeeeeeeeeeeeeeeenge"

, all these singers have something in common, but he reminds of Ya Yogo great singer who can do all voices but so weird that you wouldn't picture normal singer to sing like that.
Nono Fudji: I'm not talking just watch the video:
Add any other singers you know are so weird.
