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 i.e a bus or subway train, parking lot, or building lobby.
It is often viewed as an example of punk rock's idealistic "do it yourself" philosophy (which aimed to achieve underground artistic success without commercialisation by avoiding mainstream corporate record labels) being applied via modern communications technology, in a way which would not have been possible before the advent of the internet.
The popularity of online forums and social-networking sites has made it possible for bands to immediately disseminate news of a gig to thousands of people only hours before a performance, at minimal cost, and bypassing the traditional print and radio-based methods of publicising concerts.
[citation needed] Godard, who felt that Jefferson Airplane best represented the youth revolution of the day, wanted the band in his film while keeping to a somewhat militant spirit.
The technique first developed there because the concentrated social and geographical nature of the London music scene made it possible to generate a favourable "buzz" and ensure attendance at the events.
In another famous instance, singer Badly Drawn Boy earned £1.60 from passersby while busking outside London's Waterloo station for a day in 2003, going largely unrecognized by the public.
