Music of 428: Shibuya Scramble and Canaan

428: Shibuya Scramble is a visual novel video game developed by Chunsoft and published by Sega. The game was released in 2008, and spawned the sequel anime series Canaan, created by Type-Moon and animated by P.A. Works and aired in 2009. The music of 428: Shibuya Scramble and Canaan spans two soundtrack albums, four singles, and one character song album.

The soundtrack of 428 was primarily composed by Hideki Sakamoto and Naoki Sato, with 9 tracks done by guest composer Shingo Yasumoto. The soundtrack is varied in genre and style, which Sakamato said provided the composition process with several obstacles. The music was released on a soundtrack album by the label Lantis on February 4, 2009, with three discs and 73 tracks. J-pop artist Aya Kamiki performed the theme song to 428, "Sekai wa Sore demo Kawari wa Shinai", a rock song that describes positivity despite an unchanging world.

The music of Canaan, consisting of 101 tracks, was headed primarily by Hikaru Nanase. A three-disc soundtrack album, titled Ai, was released by Lantis on November 25, 2009. The opening and ending themes to Canaan were both of their artists' major debut singles, released by Lantis. The opening "Mind as Judgement" is a rock song by Faylan, whilst the ending theme is the contrasting, calm ballad piece "My Heaven" by Annabel. Annabel and Faylan also collaborated on an album of Canaan character songs, titled Canaan Inspired Album. Voice actress Ayahi Takagaki, as the character Nene, provided Canaan with three insert songs, which were released on a single for the lead track "China Kibun de High Tension!".

The discographies of 428 and Canaan have received positive response. The soundtrack of 428 was praised by video game and video game music critics, whereas the OST of Canaan was enjoyed by anime reviewers, who also positively noted "Mind as Judgement". Commercially, 428 soundtrack peaked at No. 131 on the Oricon Albums Chart; Canaan did not chart. "Sekai wa Sore demo Kawari wa Shinai" peaked at No. 42 on the Singles Chart; "My Heaven" and "China Kibun de High Tension!" appeared on the 60s of the chart, whilst "Mind as Judgement" broke into the top 20.

428: Shibuya Scramble
428: Shibuya Scramble soundtrack, 428: Fūsa Sareta Shibuya de Original Soundtrack, was released in Japan by Lantis on February 4, 2009, with the catalogue code LACA-9141～2. The soundtrack album was headed by Hideki Sakamoto – a video game music "veteran" – and Naoki Sato, noted by RPGFan as a composer with experience within film and anime. Produced by Natsuki Sugaya at Sound Inn Studios, the CD album release contained two discs with 73 songs, and a total length of 2:04:58–1:14:15 from the first disc's 46 tracks and 50:43 from the second disc's 27. Work was divided between Sakamoto and Sato on the first disc; the second disc was headed by Sakamoto alone, though with tracks 10–18 done by guest composer Shingo Yasumoto. Sakamoto also covered the second-disc song "Letter" with his band, Hideki Sakamoto Trio, on their eponymous debut album.

The soundtrack of 428 features a variety of themes, instrumentation, and genres. The eponymous main theme is a jazz piece with heavy use of horns, whereas the final nine tracks are composed with string instruments in an acoustic motif. Comparing the soundtrack with his work on Castlevania Judgment, Sakamoto expressed in an interview that there were more unique obstacles during the production of 428. He attributed this to the varied amount of styles, recalling that genres such as techno, funk, and classical were also featured throughout the OST.

The album made its one appearance on the weekly Oricon Albums Chart on February 16, 2009, charting at No. 131 with 1,121 documented sales. The soundtrack received a nomination for Best Score — Western Localisation at Video Game Music Online 2018 Annual Game Music Awards, but was eliminated before the runner-up. Bob Richardson reviewed the soundtrack for RPGFan. He praised the mixture of genres and instruments, commenting that the tracklist would have something suitable for most listeners. Richardson did observe that the variation could lead to disunion between neighboring tracks, but brushed this off as a "small price to pay for a set of phenomenal individual pieces." Richardson positively noted Sakamoto, Sato, and Yasumoto's work on the soundtrack and praised their cooperation, but particularly called the last nine tracks, done by Sakamoto in a "deeper" classical style, among the best pieces featured. The music was also praised by game critics.

"Sekai wa Sore demo Kawari wa Shinai"
The main theme to 428: Shibuya Scramble is the song "Sekai wa Sore demo Kawari wa Shinai", performed by rock singer Aya Kamiki. Composed by Aika Ōno, the song begins with a strings-based intro before transitioning into a rock style. The lyrics emphasizes positive towards the tomorrow, after initially opening with a bleak description of an unchanging world. The song was released by Giza Studio on December 3, 2008, marking Kamiki's 10th single. "Sekai wa Sore demo Kawari wa Shinai" received a marketing campaign alongside 428, named "428 × Aya Kamiki" Shibuya Jack, which included billboards, the song's usage as background music in public areas, and live performances. A music video was released on a web page for Kamiki and Chunsoft's collaboration, featuring characters from 428 traversing a nighttime Shibuya. It reached No. 42 on the Oricon Singles Chart, with 4,378 total documented sales during its three weeks on the chart.

The soundtrack did not appear on the Oricon Albums Chart. Anime News Network writers Theron Martin and Luke Carroll both touched on Canaan soundtrack during their reviews of the series. Carroll praised a fitting ambiance during tense and action scenes. Martin agreed, and also complimented the score for its subtler tracks, but felt that it would "[push] things" too far on occasion. Carroll summarized the music as "decent" whereas Martin called it a strong musical score. Both reviewers rated the soundtrack an A−.

"Mind as Judgement"
"Mind as Judgement" is the opening theme to Canaan. It is the major debut by singer Faylan, and was released as a single by Lantis in Japan on July 22, 2009, with the catalogue number LACM-4630.

Carroll also praised the song for providing Canaan with a high-action opening. Both reviewers noted the polarizing themes between "Mind as Judgement" and "My Heaven".

"Mind as Judgement" has been performed live by Faylan on multiple occasions and has been included in various albums. Altered versions have been included in Canaan related albums: a ballad cover by Faylan was the lead track of Canaan Inspired Album, and a short version of the song was recorded as the final track of the Canaan soundtrack album. The song was performed at Faylan's Happy Soul Dance tour; the performance was later included in the DVD for the early edition of Faylan's second album Alive (2011).
