You are surely talking about Konkoba (the great harvester). It's a Guinean rhythm.
It's a rhythm primarily played for harvesters.
Its particularity is that it is a ternary rhythm in 3 beats (like Koreduga).
There are many versions of it.
-You can find one in "Chants et percussions malinkés, vol 1", Famoudou Konate
-You can find another in "Fadouba Oulare", Fadouba Oulare
-There is a 3rd version which is often played, but I can't remember where you can hear it
-There is a 4th version you can hear on "Come Drum", Fadouba Oulare
Also there is a modern version for ballet dancing. It has almost nothing to do with the previous ones regarding the speed. It is played very very fast, in order for the dancers or the acrobats to show their skills.
Take a look at this video, first part = usual way of playing konkoba, second part = modern ballet version:http://www.youtube.com/watch?v=ArNVhum0xxM
