Chroma Key has been played on NTS in shows including Cosmic Dreamer Radio, featured first on 26 March 2018. Songs played include Lunar.

Chroma Key is the brainchild of ex-Dream Theater keyboardist Kevin Moore. It takes the form of very mellow and slightly somber, fairly ambient experimental progressive rock and electronica, which is predominantly keyboard-centred, having practically no common characteristics with what Moore had done with Dream Theater.

Moore has released three albums as Chroma Key: Dead Air for Radios (1998) You Go Now (2000) Graveyard Mountain Home (2004)

All Chroma Key releases have been self-produced and recorded in Moore's home studios, the locations of which change from album to album.
