The musical theme of Star Wars has become a defining classic amongst the world of music. I’d be surprised of any one person heard the music and did not know where it was from.
Then there are flash-mobs. Groups of people that come together, from seemingly out of nowhere, and dazzle the citizens in the area. I’ve seen (on TV) some pretty cool stuff, though I have yet to see one in person.
Now, pull those two together, the music from Star Wars and the idea of a flash mob, and I present to you, a flash orchestra!!!
I’d bet that was a pretty cool surprise to get caught in the middle of.
