Laba Sosseh is perhaps not the best sonero to come out of Africa, he does have some of the best recordings. And he has inspired and still inspires a great number of other singers.
Examples of these great recordings have been released on CD, notably on the Dakar Sound label.
I especially like the sweaty ambiance of the live tracks.
"El Sonero De Africa" which was released in the 1970s on the Senegalese N'Dardisc label has a very different sound, but still is one of my favorite Laba Sosseh albums. It contains some superb covers of classic Cuban sons (including an near ecstatic version of "Guantanamo"), plus one track ("Mama Yassima") which the sleeve contributes to Laba Sosseh himself, but which -if I am not mistaken- is in fact by Jean-Serge Essous.
Here is the album.
