At the 5th Indira International Innovation Summit, the post-lunch slumber was blown away to bits by an amazingly talented group of drummers from South Africa called Drum Cafe. They are not just performers but great crowd collaborators. The audience got lots of drums and they were encouraged to join in producing music and play in syncronony. The crowd absolutely loved it. It was by far the most entertainin session for they were not just passive listeners but active participants.
