On the replica cover Han Bennink is credited playing two rare instruments. One is called Gachi which is a slim metal trumpet to be found in the surroundings of lake Tchad, at the Kanuri in Nigeria and at the Fulbe in northern Kamerun. It is usually made of two parts (about 2 meters long) and it has normally two tones a fifth apart.
