Christopher Sisk (born March 26, 1979, Tennessee, USA) is an independent ambient/electronic musician and sound designer whose work combines traditional electronic and ambient music styles with various experiments in longform generative systems and sound collage.

His most notable works are his 2011 album Background Musics - an album of ambient music designed to act as a film score for commonly shared human moments and experiences and his series of albums and website called "Light: A Generative Album" which expands his generative music techniques and ideas into a much larger scale as well as several other long-form ambient releases.

Christopher is currently working on new generative projects as well as more releases for the Light series and website. He has previously released music under the names Creature, Sisk, and Smpl, and works with friend John Maplethorpe as one half of Todd and Tucker.
