The big companies always have flashy big comeback stages and these people can't even afford a simple stage. ;_;
http://en.wikipedia.org/wiki/Guerrilla_gig
There are two major elements[citation needed] that characterise a guerrilla gig. The first is similar in concept to a flash mob, and involves a band or artist performing in an unexpected, sometimes unannounced, setting not designed to accommodate live music, such as on a bus or subway train, parking lot, or building lobby. The second characteristic involves their being arranged very quickly and without the typical processes of publicity or advance ticket sales. They are usually announced through various internet message boards as well as by text messages and sometimes last-minute flyers.
Basically they just perform randomly on the street.
Wow it's almost as if I'm drunk too, I have so many spelling errors :c
