The concept of the algorave first popped up as a pre-party for the 2012 supercollider festival, and is now growing legs. The basic idea is to run or live code repetitive sonic algorithms in dark rooms. This month there are algorave live PAs in London, Karlsruhe and Mexico City, spreading to Sydney in 2013.
An algorave is defined as one where people dance to sounds wholly or predominantly characterised by the emission of a succession of repetitive conditionals, a reference to the definition of house music in the anti-rave Criminal Justice Act passed in the UK in 1994.
There is now an algorave website, where you can keep up with algorave alerts.
