This led Moore to form OSI with Fates Warning guitarist Jim Matheos in 2002, a band which combines progressive metal with electronica.

After graduating from high school in 1985, Moore briefly attended SUNY Fredonia, where he studied classical music, before returning home to form the band Majesty with childhood friends guitarist John Petrucci and bassist John Myung, who had recruited drummer Mike Portnoy (a fellow Long Islander) during their short enrollment at Berklee College of Music.

Singer Chris Collins handled vocal duties for Majesty, but he was subsequently replaced by Charlie Dominici (and eventually James LaBrie) and the band was renamed Dream Theater.

Shortly before the album was mixed, though, Moore announced to the rest of the band that he wished to concentrate on his own musical interests and would be quitting Dream Theater.

After leaving Dream Theater, Moore moved to Santa Fe, New Mexico, and started writing material for his solo album.

A demo tape known as Music Meant to Be Heard was shared among fans, and the songs included many spoken-word samples from interviews Moore recorded during his cross-country travels.

The album featured a dark, ambient sound, closer to Peter Gabriel and Tori Amos than the complex and intricate Dream Theater style.

The resulting album is titled Graveyard Mountain Home, which included a DVD containing the movie set to Moore's music.

Musically, it can be described as a mixture of Chroma Key's dark, melodic focus with the guitars and heaviness of Fates Warning and Dream Theater.

In September 2008, Moore announced on his website that he had been working for several months with Jim Matheos and drummer Gavin Harrison (of the band Porcupine Tree) on the third OSI album.

In 2004, Moore relocated to Istanbul, Turkey, and composed the soundtrack to the horror film Okul (The School) which was subsequently released as a solo record titled Ghost Book.

The film, Küçük Kıyamet (The Little Apocalypse), tells the horrific tale of a family who decides to rent a summer house by the seaside.

Its soundtrack CD Shine was self-released December 2010 after a funding campaign on Kickstarter[2] Both films, Okul and Küçük Kıyamet, were based on books written by Turkish author Doğu Yücel.

In September 2013, Fates Warning vocalist Ray Alder revealed in an interview that Moore returned to the United States and studied to become a doctor.

He earned his Doctor of Osteopathic Medicine from Des Moines University in Iowa and completed his psychiatry residency at Garnet Health Medical Center in Middletown, New York.

He still used his Kurzweil K2000 and a Yamaha CP-70 piano, first release "dead air for radios" is all k2000 and cp70 On "You Go Now", in addition to this, an Access Virus, Moog Memorymoog Plus and a Nord Lead rack.
