Unfortunately I didn't get to go to this years Google Zeitgeist event a few weeks back, but I know a man that did and he came back raving about the final session of the first day – a talk by reknowned Isreali conductor Itay Talgam. Having now seen it, I can see why. Itay uses the metaphor of conducting to talk about leadership and collaboration: the importance of opening space for interpretation within organisations; the price of over-control; what he calls "doing by not doing". It's fascinating. And well worth half an hour of your time.
