Here's a short video doc of Florian Hecker's installation Pentaphonic Dark Energy at Sadie Coles HQ gallery in London from last month. Technically impressive with it's swish speakers: expensive Genelec's from Finland and two highly directional custom built ones. The recording can't do the spatial experience justice; in such a small room the sound could seem as present as if it where hovering somewhere near the centre of one's forehead, then phasing about the gallery quickly giving one a slightly off balance feel. A perverse sonic Feng Shui.
