ImprovEverywhere is a group who conduct a lot of flash mobs all over the US. In this particular video that is on youtube.com. They gathered 207 people in New York's Grand Central Station to do a huge flash mob. They choose and exact second in which they would all stop randomly in whatever position they were in and would stay there till the specified time. They were just randomly everywhere and doing normal everyday things, but all did like they agreed to and stopped. People were just so surprised. They didn't understand what was happening and why all these people just stopped. Some people were convinced they were protesting something or trying to get across a message.

In the online article that I read it gave the definition of what a flash mob is and then it went on to explain the origins of flash mobs. The first flash mob in 2003 was suppose to poke fun at society and conformity and in doing it started a new way to conform without appearing to conform. The article then lists different countries flash mobs and the largest one that I could find was an international pillow fight.

In the online article "Playing Music can be good for your brain/Stanford study finds it helps the understanding of language", by Sturrock it goes over research done by Stanford. In their study they had two groups of adults, musicians and non-musicians. They found that musical experience helps "the brain improve its ability to distinguish between rapidly changing sounds that are key to understanding and using language."
