@odenspecial Na - that's just someone dancing up to play the dundun. He plays exactly the same sequence 4 or so times in a row then improvises around them at the end, which is what people tend to do when demonstrating / recording at the end of a workshop. Plus he doesn't play any signals as such between phrases (which you would do to tell the dancers to change step). Anyway, lovely solo. Lots of variations on the classic soli phrase.
It wasn't even that. It was giving the taste of what was to come that week of learning and sharing. So, yes, he had to stay within a certain frame, otherwise we wouldn't have started the morning after.
Emancipate yourself of dogmas about only a certain way of playing djembe. Before ballet and professionalism of djembe, it was about joy and self-expression.
