First time I've heard this song, he sounded just like Emeneya.

yes,this was blaise,it was the first song ever recorded by wenge,along with  a song of zing zong and  a song of jb if i remember well
the only songs zing zong played on in wenge

Someone told me that JB was also singing differently in that era, he was singing like Debaba and I've also noticed that Aldophe Dominguez was singing differently in the song La Fille de Roi.(from 3:50)


What did lead Blaise to sing not more like Emeneya

 he certainly wanted to have his own identity,juste like before wenge, he was singing like  bozi,he is quite good in that emeneya singing,should use it again sometimes
yes indeed jb was more into debaba singing,the one who chaned the least between that era and when wenge became known was werra
