yeah its him indeed
you summed it up well,blaise does not look like it but he's one hell of a hot headed guy,he was already the first to be "causing trouble" back at the start of the serious wenge in mulolo by deciding to boycott studio over a disagreement,it took days and days of jb masela makaba werra begging him to come to sing as alain mpela who did his part did not have a mature voice enough to stand the role well,so he had to do additional chorus when all the rest were done with it
and in the split as well its his anger against werra when werra called him a coward which kicked everything to another level and which was a point of no return,because then blaise would take most of the group to prove werra a point and then associated jb knowing jb has the leadership and the visas and all that already
