The route of Nsele was dangerous. It is the fault of politicians, they had to light up that road. It was not only during concerts, also after those big MPR-meetings, Mobutu-speeches and even just a simple visits. Nsele Folis got abandoned after 1997, it's a big ruin, if you go there today you won't recognize it anymore.
Yeah, alot fans died after the concert that Reddy Amisi performed at Nsele Folis. Journalists even went to write multiple articles about Reddy having sacrified people after that incident. It hurted Reddy Amisi alot and he made even made a press-conference to defend himself, but it didn't help. Hence why he recorded the song Ziggy.
