Safe follow up their 2002 release The Air is Full with a further set of combinations of field recordings, keyboards, microphones, vocals, no-input, metals, with the end result reminiscent of Nurse With Wound. Origin of Species comes from live, improvised performances using those materials. Except for the closing track, nothing was added to those live recordings, so as to preserve the clash between pre-recorded materials and improvisations. Darwin realised that species were not fixed, but accretions of different features, combining more or less at random, but resulting in identifiable forms. As here. This cd is double and limited to just 50 copies, with cd 2 a handscratched copy of the recordings, hopefully randomising the sounds further.
