Flow Festival

Bon Iver (Wed), Flying Lotus, Asap Rocky, Four Tet With Caribou (Fri), The Black Keys, Ane Brun, Nicolas Jaar (Sat), Björk, Feist, St Vincent, The War On Drugs (Sun), plus Frank Ocean, Bobby Womack, Hudson Mohawke, Korallreven and Ritchie Hawtin. Having only kicked off in 2007, Flow Festival is relatively new, but for one weekend every year since, Flow has taken shape and grown within its confines of a disused power plant. It's easy to get to from the the centre of Helsinki and already has some huge names such as Björk and The Black Keys confirmed for 2012, as well as a DJ collabo between Four Tet and Caribou.
