Music, including singing as well as the playing of instruments, has been a key element of the human condition for millennia. Unfortunately -- at least in the United States -- music has become more of a commodity, to be enjoyed passively and non-interactively.
The rise of mass media is probably at least one of the culprits.

Street Music blurs the distinction between producer and consumer of music as well as the distinction between formal and informal venues for music production and consumption.
Although street bands, including many of those found at Honk Fests, can be found at protests (including the Infernal Noise Machine (image below) that supported the demonstrations against the World Trade Organization in Seattle in 1999), their actions are often political to a large degree by virtue of their publicness in an era of electronic or other formalized or mediated forms of music consumption.
