Kevin Moore (born May 26, 1967) is an American keyboardist, composer and the founder of the Chroma Key music project. He is also a former member of American progressive metal band Dream Theater, co-founder of the progressive rock supergroup O.S.I., and a composer of film soundtracks. Throughout his career, he has become known for his emotional music and lyrics, nomadic lifestyle and use of spoken word samples. Moore started his music career in progressive metal band Dream Theater. He contributed music and lyrics to the band's first three studio albums, but left the band during the mixing process of Awake to pursue his own musical interests. Starting with 1998's Dead Air for Radios, he has released electronica, ambient music through his solo project Chroma Key. Moore has guested on several albums, including three Fates Warning albums. This led Moore to form OSI with Fates Warning guitarist Jim Matheos in 2002, a band which combines progressive metal with electronica. The fourth OSI album, Fire Make Thunder, was released in March 2012. Moore has worked on other solo projects since leaving Dream Theater. While living in Costa Rica, he produced a bi-weekly radio program for Radio for Peace International; a compilation of this work was released as Memory Hole 1. While living in Turkey, Moore produced the debut album of Turkish band Makine and wrote soundtracks for two Turkish films. The soundtrack for the first film, Okul, was released in 2004 as Ghost Book. The soundtrack for the second film, Küçük Kiyamet, entitled Shine, was released in 2010.
