Songwriter / poet Leonard Cohen gave a concert in Tel Aviv a few days ago. In "Tower of Song" he kept the audience craving for The Answer (to all mysteries of life) for almost 2 minutes. The audience got really excited, the backing vocals had to work hard... Listen to the entire song, or skip through to 6:00. No, no spoiler here. The video below is not the Tel Aviv concert, but a different performance in the same tour.
The presentation lesson. Many communication philosophies such as Barbera Minto's Pyramid Principle (used by McKinsey) advocate to present your conclusion first, then provide backup and logic. Very efficient, at every single point in time, the audience knows the key message of the presentation. Sometimes humor, suspense, drama and good story telling might actually do a better job in getting a message across though. Highly structured presentations are not always the most memorable ones.
