I enjoyed the Water Drums clip, but only because of the novelty of the sound, tbh. Considered as a piece of music, it doesn`t seem to go anywhere.
Frownland`s contribution scores really high in terms of authenticity. Congrats on being one of very few MB members to show any interest in plantation work songs - I discovered the limited appeal of this kind of music when I tried to revive interest in this thread:-

Here are three takes on the theme of tribal music:-
(a) must be authentic because of the unselfconscious boob display:-
(b) deliberately composed "tribal" music that usually ends up sounding pretty cheesy:-
