TED talks are lectures of 18 minutes or less heralded as "ideas worth sharing" in the areas of technology, entertainment, or design. For a little more background on the series, you may want to read this entry on Wikipedia. This particular talk should be of interest to the musicians reading this blog. The speaker and former conductor Itay Talgam uses video of six twentieth-century orchestral conductors to illustrate the concepts of control and collaboration. I found it to be a very interesting piece.
