Back in the days it very normal to sing with only 3 or 4 mics. Back in the 60s it was already to much when you had 4 singers on stage. They were prefering duets and 3 singers as max. Emeneya tried to replicate it with Makolin (wanting to copy the duet of Tabu Ley and Paul Ndombé) when recording albums in the mid 80s. From the 70s most bands started to sing with 4 mics and 5 when it was a band of a solo-artists. It because of Koffi Olomidé that they started to use 6 mics and later even going far with 8 mics. I guess because of having to many talented singers in his band and him not wanting to see them wait for x & y to sing song with the 4 mic system. Papa Wemba himself kept that system of 4/5 mics until his first Zenith of 1999 where he used 8 mics for Nouvelle Ecriture. Clan Wenge ended up by adopting Koffi's system of 6 mics.
About this concert, most of QL-singers were left behind during this tour. Koffi only brought Willy Bula, Suzuki, Babia Ndonga and Scola Miel. Babia was put in jail and Scola Miel decided to leave when QL was about to tour in the US which made Koffi just sing with only 2 singers during this tour until their return to Kinshasa.
