Very active ambient that almost, but not quite, morphs into noise. I often put on ambient music to either let my thoughts wander or to push away outside stimulus in order to focus on a particular topic. When listening to Whirr you think about what Whirr wants you to think about. When listening to the masterpiece of micro-editing that is Black Island, Whirr directs you around the island. The ability to tie disparate soundscapes together into what is essentially an ambient novel makes this album genius. Very highly recommended.
