RahXephon O.S.T. 2 is the secondsoundtrack album from theanime seriesRahXephon. All music and lyrics are byIchiko Hashimoto and performed by her. She is again joined by her sister Mayumi Hashimoto on the song "Yume no Tamago (Egg of the Dream)".Houko Kuwashima, the voice ofQuon, also sings on this album.

Hashimoto described this as "more organic" thanthe first soundtrack, and it contains some music that was recorded after the series had begun airing.^[1]

The theme of "La, la Maladie du Sommeil" is fromPolovetsian Dances. This track is featured on the albumJunsyoku Brilliant (緋色brilliant) (VICL-61796).

The track "Huge Suites" (sample^ⓘ) features a melody played in turn by different instruments, over asnare drum rhythm and acounter-melody, beginning quietly and rising in acrescendo. This track thus shares some of its structure withMaurice Ravel'sBoléro. The initial rhythmic pattern in "Huge Suites" is simpler than that inBoléro, consisting of only 6 beats. The track as a whole is more ornate, however, with transitions inmelody theme and rhythmic pattern. While the main melody ofBoléro transitions back and forth between two themes ( ), this track transitions back and forth between four themes. The first rhythmic change is at 1:23, coinciding with the third theme transition. At 2:00, the string section returns to the original rhythmic pattern while the percussion does not; the previous rhythm thus becomes a counter-rhythm. In contrast,Boléro keeps the same rhythmic pattern going all the way until the end. "Huge Suites" has its final transition at 2:18, where the counter melodies end and both the rhythm and theme dive into a crescendo that builds for the last 40 seconds of the track. The main theme from this track is also used for the song "Brave" on thenext album.

RahXephon O.S.T. 3 is the third and lastsoundtrack album from theanime television seriesRahXephon, but it is followed by thesoundtrack to theRahXephon movie. All music and lyrics are byIchiko Hashimoto and performed by her and supporting musicians.Houko Kuwashima, the voice ofQuon, sings an intentionally distorted theme fromAlexander Borodin'sPolovetsian Dances on track 18 "Way to the Tune".

The album opens on "Midday Dream", a slightly chaotic jazz improvisation that is followed by two tracks with shouting vocals: "Guten Morgen" and "First Explosion". "Mad Wing" takes the chaos to a crescendo. "Brave" has a fast-beat backing track heavy onpercussions with occasionalelectric guitar solos and English vocals performed by Hashimoto; the melody is the main theme from "Huge Suites" on theprevious album. Track 6 "Tailspins" is a fast-beat track that was used for the air battle inthe series episode 1.

Tracks 7 through 12 arepiano sonatas; the first one, "Innocent World", is playful and up-tempo while the rest are calmer, meditative pieces similar to "Solitudes" fromthe first album.

Track 14 "Writes herself" was used for episode 19, as was track 16 "Second Sorrow", which is a version of the ending theme "Yume no Tamago". Track 15 "Reverse Point" is a piece performed by a doublestring quartet (anoctet) and used for the planning scene in episode 21.

"Object Float" is used in the "tuning", along with "My Soundscape", which also appears in some "eyecatches" (commercial bumpers) in previous episodes. "Way to the Tune" starts out as a distorted version ofGliding Dance of the Maidens fromPolovetsian Dances performed byHouko Kuwashima, receding into synthesizerambience.

"Before you know" is used for the ending credits of the final episode. It starts out as symphonic piece withfrench horns, strings,harp andwood blocks.Clarinette andflute then play the lead, joined by strings. A string bridge takes the track to a transition where the lead is played by drawn strings accentuated bypizzicato violin, while an electronichi-hat and brush beat fades into the symphony. The melody transitions into a version of "Yume no Tamago", brought to the fore withtubular bells andgrand piano, while a pronouncedsnare drum is added to the beat.

The final track "Previous notice" is a short and fast composition for piano anddrum kit that was used for the episode previews.
