Aussie rock band Powderfinger have tapped into the crowdsourcing trend in a bid to create a little hype before their upcoming tour. Just this week, they’ve had 3 impromptu concerts in Sydney
, Melbourne and Brisbane, announcing where they are playing 30mins before on Twitter. The Sydney and Brisbane guerilla gigs had about 1,000 people rock up, mainly office workers. Nothing majorly new here, but it was cool nonetheless and a bit of fun.
