So nice... Has any band done this?  I know of double synte and double drum set.

what a good way to end your work time,i hope somebody will try it in concert,koffi once tried it in a rehearsal but never in a concert yet,i think it would be complicated to set up

Yeah Franco in 1971 after Tabu Ley performed at Olympia. He was jealous that Tabu Ley introduced the drum, so he decided to perform with two bass-players  and two drummers on stage. But everybody forgot about it quickly and there isn't any footage (so stupid that RTNC lost all footage in 1997).  Seskain Molenga once also talked about that in his interview with Ado Yuhe.
