Don't know too much about this band, apart from that they were from Gabon. They played Congolese style, and I can say they did it well. Here is a great tune from their repertoire:

This is one serious effort

I like the rhumba bit, and the vocals are very well arranged. have tried to look for more information on them also but unfortunately there is very little on them in the Net.

Gabon has been a domicile for a number of Zaireans for a while now, and I fondly remember Franco's FC 105 tribute.
