One thing I can say about Roga Roga is that his technique/sound is a bit different than most.  Most tracks (non extra music) that he has been featured on, I can immediately tell it is him playing based on his approach.  There are only but a few that have this distinction.

Several guitarist from his circle plays that way, probably borrowed the style from him. A good example is the song: Tapis Rouge of Universal Zangul. Very similar in style to Obligatoire, recorded about the same time.

Yes I have noticed that Roga's solo are between the best U have heard, I don't know why, but it seems that After Kapaya is one of the few guitarist left who can play that fast aggredisce Sebene, I hate that people were saying that Extra Musica were a copy of Wenge Mysica (which they kinda was) because these forced them to change their style, it would have been too nice to have am aggressive style of Seben from Extra Musica through9ut the years instead of them being forced to change that Etat Major, Amnistia Hsalai style who was making them compete and somet8mes outmatch Kinshasa based groups

This is an unpopular opinion but I think the La main noire generique was way better than Obligatorie. Obligatorie is a very monotonuos generique that had
a strong start to it. The rest of the album was amazing though.
