In light of protests in Hong Kong this week, I'm re-posting this: Over the past year, I've chronicled here the global phenomenon of flash mob musicians (and often singers) performing Beethoven's "Ode to Joy," to wild reactions in, for example, Spain, Lithuania, and Hartford, CT. One of best I've found (see below) possibly the best of all, so far, in Hong Kong, under the banner of "Ode to Change." But the flash mobs also take place in more modest venues such as a farmer's market in Austin, TX. Or a high school. Or a college, with dancers. All of this, of course, closely tied to our new film, Following the Ninth.
