in this interview of keyboard player desy kalala the guy who had the legendary kalayi boeing partition,he says he was born in 1963 and before wenge musica he was in a group of matadi with jipson back in 1988 which surprised mbuta likasu since mbuta is 50 and always knew that the likes of fally ferre mamale and co were his generation,and if jipson was that type of age then he'd have been maximum 15  then,because desy said he never felt like a 10+ years gap with jipson
in the rest of the interview he gives interesting anecdotes like alain makaba and masela fighting while on european tour,werra's bag caught with weed at belgian hotel and telling ekokota  to say it was him and they were handcuffed and so on

During the European tour when they were recording Les Anges Adorables and Pentagone, I noticed that they didn't have a keyboardist present. Which makes sense because Alain Makaba played keyboard on both albums, when did Theo Bidens officially join? Was it after they released Pentagone? Because I see that there was a keyboardist during their performance at Grand Hotel Kinshasa in 1994 @ 24 minutes (it's hard to tell who it is, the footage is grainy)



From my research, Theo Bidens joined around 1995. However, it seems he got left behind during the recording of Pentagone and Feux De L'Amour.

his entrance was a bit like ficarre's some sporadic appearances here and there as a stand in for one two years then officially joined before pentagone
