If you havent seen it watch the 2002 zenith concert where he performs. There are a few other concerts on youtube where he performs it. It's a shame he performs Kibuisa mpimpa more than operation dragon at concerts, when I think the latter is a far more superior generique.
Also did this guy use a program to create this instrumental because I can still mildly hear some voices in the background. If so he should definitely do this with other songs. Why do they never release official instrumentals of their generiques and sebene songs?
