Dark Flow Electronics
The electronics for the piece were created using Ableton Live. These are screenshots of the arrangement window for the piece. Redshift begins with a mix of software synthesizers and samples of glass. Quasar begins with samples of humpback whales, a bowed cymbal, and a low cello drone. Clusters contains samples of voices taken from number stations around the US, and a clip from the SETI website.
