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. Most of these songs were later released in 1999 on a limited-edition CD called This is a Recording.  In 1998, Moore released his first solo album, Dead Air For Radios, under the name Chroma Key on his self-created record label, Fight Evil Records. Mark Zonder and Joey Vera of Fates Warning served as his support musicians for that record. The album featured a dark, ambient sound, closer to Peter Gabriel and Tori Amos than the complex and intricate Dream Theater style. In hindsight, Dream Theater fans noticed that Moore had subtly explored this style of composition in "Space-Dye Vest."  In 2000, Moore moved to Los Angeles, California, where he recorded the digitally-themed You Go Now. The line-up for that record was Moore, David Iscove (guitars) and Steve Tushar (loops, programming). During his westcoast stay, Moore earned a BFA at California Institute of the Arts, where he created a little-known documentary called Octember Revolution, which depicted a Southern California gated community intervention. He then moved to Costa Rica, where he worked for Radio For Peace International, producing a bi-weekly activist radio program. In fact, some of Moore's work on Radio for Peace International was later released in an internet-only album called Memory Hole 1.  In 2004, Moore scoured public domain films looking for one that exuded a certain mood, intending to write a pseudo-soundtrack to it. The film he chose was Age 13, an educational film from the 1950s, originally for use in schools. He took the existing film, slowed it to half speed, and let it dictate the moods, textures, and even running times of the songs he wrote to it. The resulting album is titled Graveyard Mountain Home, which included a DVD containing the movie set to Moore's music.
