Context paragraphs:
Graveyard Mountain Home: Graveyard Mountain Home is the third studio album released under the name Chroma Key by American keyboardist Kevin Moore.  It was released on November 8, 2004 by InsideOut Music.  Moore originally started work on the album in 2003, planning to release a less electronica-influenced album than previous Chroma Key albums, but put it aside to work on the first OSI album.  He then moved to Istanbul, Turkey, where he wrote "Ghost Book", the soundtrack to the film "Okul".  Enjoying the experience of writing music to film, Moore scrapped his previous plans for the third Chroma Key album, instead writing an album as an alternate soundtrack to an already-existing film.

Symphony X: Symphony X is an American progressive metal band from Middletown, New Jersey.  Founded in 1994, the band consists of guitarist Michael Romeo, keyboardist Michael Pinnella, drummer Jason Rullo, lead vocalist Russell Allen and bassist Michael Lepond.

Voices in My Head (EP): Voices in My Head is an EP by the band Riverside.  It was originally released in 2005 through Mystic Production, but re-released in 2006 through InsideOut Music.  Lyrically, the EP is not a part of the Reality Dream series even though it was released between Out of Myself and Second Life Syndrome.  The EP contains many acoustic passages on songs like "Us" and "The Time I Was Daydreaming" that do not appear again until the band's third full-length album, Rapid Eye Movement.  A video for the song "Acronym Love" is included on the InsideOut re-release and can be viewed on a computer.  The live version of "I Believe" is played with the standard instruments instead of an acoustic guitar, which is unlike what is heard on Out of Myself.
