The track "Huge Suites" (sampleⓘ) features a melody played in turn by different instruments, over a snare drum rhythm and a counter-melody, beginning quietly and rising in a crescendo.
"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.
Houko Kuwashima, the voice of Quon, sings an intentionally distorted theme from Alexander Borodin's Polovetsian 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".
"Brave" has a fast-beat backing track heavy on percussions with occasional electric guitar solos and English vocals performed by Hashimoto; the melody is the main theme from "Huge Suites" on the previous album.
Tracks 7 through 12 are piano sonatas; the first one, "Innocent World", is playful and up-tempo while the rest are calmer, meditative pieces similar to "Solitudes" from the first album.
Track 15 "Reverse Point" is a piece performed by a double string quartet (an octet) and used for the planning scene in episode 21.
The melody transitions into a version of "Yume no Tamago", brought to the fore with tubular bells and grand piano, while a pronounced snare drum is added to the beat.
The final track "Previous notice" is a short and fast composition for piano and drum kit that was used for the episode previews.
"Hemisphere" was used as the opening theme for Yutaka Izubuchi's anime series RahXephon, in which Sakamoto also played a character.
Not included is a re-arranged synthesizer version of "Hemisphere" that appeared in the Super Robot Wars MX game itself.
The lyrics to the title track were written by Yuho Iwasato and the music was composed and arranged by Yoko Kanno.
It was used as the ending theme for the anime television movie RahXephon: Pluralitas Concentio in which Sakamoto also voiced a character.
The story is about Ayato receiving a box of chocolates as an anonymous Valentine's Day gift, and the quest to find out who sent it.
