Describing himself as an armchair ornithologist, Anderson says he became fascinated by Darwin's observation of how birds indulge in ornate creations that do not alway sreflect the purpose for which they were intended...The idea of evolution 'pushed me towards gradual change [as a determing factor in the music]. I started with one chord - a sonority that, when you hear it, will be three-dimensional. I worked a lot on it, to get a depth of sound. There are very low notes on bass clarinet and harp, and very high string harmonics, the combination of which leads to a strange sort of resonance.''
