Sentinel is the experimental musical outlet of Jason and Mykel Langley. The Sentinel sound is a combination of dark ambient drones, glitchy synth melodies and experimental beats that depict a decaying world of strange beauty and undelying unease, always sticking to the principals of reflecting the world around us, yet showing the world as changeable. Sentinel has released four albums and two singles since its 2009 inception, and has recieved remix contributions from diverse acts such as Digital Deformation, DSM and Prolefeed.
