Kuba drum Congo
„The cultures of south Zaire, east Angola and the north-west province of Zambia are mostly characterized by various influential royal dynasties. The best-known drums of the region come from the Kuba kingdom, situated between Kasai and Sankuru. Their skins are attached using a characteristc technique. A strip of leather is placed around the top of the body and nailed to it; the skin is then stitched to the leather strip."
excerpt from the book: Andreas Meyer - Afrikanische Trommeln West- und Zentralafrika, Berlin 1997 p.243

Such drums were employed only in rare circumstances, such as the investiture of nobles.
Die Trommel wurde nur bei besonderen Anlässen, so z.B. bei Investiturzeremonien verwendet.
