Arthur King is a group that makes experimental music with a broad, cinematic feel that often has a fairly ambient feel with intricate electronic layers, but depending on the project, could also acquire a percussive nature that approaches club-like beats at times. They are led by composer and multi-instrumentalist Peter Walker, who is accompanied by a fluid group of musicians that regularly includes another multi-instrumentalist, David Ralicke. Their music feels well-grounded despite the fact that it is improvisational. Changing Landscapes is their multi-media series that focuses on specific locales and the particular sensations they evoke in the musicians, while the Unknown Movie Night series is where the band live scores a movie without any prior knowledge what movie they will be scoring for.
