The caption on the album page reads: 'Niapu's orchestra, was one of the best that I have ever heard. They played weird and frenzied music, which possessed unusual rythm [sic].

They have a great variety of drums and instruments.

In the top right hand picture [Y304N/118] looking from right to left is - Edundu, the big drum. Next four Ebrundru's which are brass studded and slung from the shoulder in play; and then a few small dog shaped drums which they call nec-bo-bo. Behind is negbanzi a huge ivory trumpet, attached to the mouth of this is a long wooden cylinder bound with leopard hide.

Another instrument is a brass bound pole which has hundreds of small bells attached to it, this is shaken up and down continuously all the time they are playing'.
