Pepe Kalle was quite a character and very well known in the world of congolese and east african pop. According to this great summary of his discography from Frank Bessem, this cassette came out about 1990. I already have some Pepe Kalle stuff and know that he is quite well known, but now I'm going to have to check him out further. This kind of fairly fast Soukous with really bright metallic guitar just really grabs me. You can cop some really fresh Pepe vinyl from 1981 on the amazing Ylow blog here.
I didn't put the last track on here because it doesn't sound like it is Magali and I'm not sure what it is called.
I'm not sure what to think of the fact that he was famous for having dwarfs who performed with him. It gets more freaky when the dwarf starts to hump the other dancers halfway through the vid.
