Supercell (band)

Supercell (stylized as supercell) is an 11-member Japanese pop rock band led by musician and songwriter Ryo, which formed in 2007 as a dōjin music band. The other 10 members are artists and designers who provide illustrations in album booklets and music videos. Supercell started out by making use of the Hatsune Miku Vocaloid singing synthesizer to produce vocals for songs submitted to the Nico Nico Douga video sharing website. The popularity of the songs led the band to release their independent self-titled album Supercell (2008). Supercell later signed to Sony Music Entertainment Japan and had a professional release of their Supercell album in March 2009, which was updated with more songs.

Supercell made a transition to vocalist Nagi Yanagi with their debut single "Kimi no Shiranai Monogatari" (2009). Two more singles featuring Yanagi were released in 2010, followed by Supercell's second album Today Is A Beautiful Day (2011), which was Yanagi's last contribution with Supercell. Following Yanagi's departure, Supercell held auditions for vocalists, and 15-year-old female singer Koeda was chosen out of about 2,000 candidates. Koeda's first single with Supercell is "My Dearest" (2011), and four more singles featuring Koeda were released between 2012 and 2013, followed by Supercell's third album Zigaexperientia (2013), which was Koeda's last contribution with Supercell. In 2019, Supercell chose the singers Ann and Gaku to be their new vocalists.

Supercell and Today Is A Beautiful Day were awarded a Gold Disc by the Recording Industry Association of Japan for having exceeded 100,000 copies shipped in a single year, and Supercell was chosen as one of the best five new Japanese artists of 2009 during the 2010 Japan Gold Disc Award competition.

2007–2008: Formation and indie releases
On December 7, 2007, Ryo submitted the song "Melt" (メルト) to the Nico Nico Douga video sharing website, and since then the video has been viewed over 14 million times. For the song's vocals, Ryo used the Vocaloid singing synthesizer software Hatsune Miku, and he used an illustration of Miku by an artist named 119 (pronounced Hikeshi) on the video without his permission. After Ryo contacted 119 with an apology, 119 responded with great interest in "Melt" and began to work together with Ryo, thus forming Supercell. More members joined Supercell since its formation, which led to 11 members by the time the group made its major debut. In an article in The Japan Times, Ryo admitted that he did not have any "big intentions" in uploading "Melt" to Nico Nico Douga and was not someone who "set out to find success" as he put it.

Ryo chose to distribute his music on Nico Nico Douga because he liked the website along with its response system, which enables user's comments to appear overlaid on the video screen. Ryo did not originally intend to use Hatsune Miku as the vocalist for his songs, and most members of Supercell did not even know of Miku until after "Melt" gained popularity. Since Ryo did not know any singers, he was recommended by his friends to use Miku, which he thought was a good idea since videos using Miku were already widely being distributed on Nico Nico Douga at the time.

In 2008, Supercell continued to release songs on Nico Nico Douga which quickly became popular. Supercell's releases of "Koi wa Sensō" (恋は戦争) on February 22, "World is Mine" (ワールドイズマイン) on May 31, and "Black Rock Shooter" (ブラック★ロックシューター) on June 13; all have received over 4 million views. Ryo composed the song "Kibō no Neiro" (キボウノネイロ), released as a limited edition image song CD with the fifth volume of Shū Shirase's light novel series Oto × Maho on July 15, 2008. The song was released in two versions: one sung by Hatsune Miku sold at Animate and one sung by the human singer Sari sold at Comic Toranoana. At Comiket 74 in August 2008, Supercell released the independent self-titled album Supercell containing their most popular songs in addition to several previously unreleased tracks. On December 12, 2008, Supercell released "Hajimete no Koi ga Owaru Toki" (初めての恋が終わる時) on Nico Nico Douga, which has since received over 3 million views.

2009–2011: Major debut and vocalist Nagi Yanagi
Supercell made their major debut with Sony Music Entertainment Japan with the professional release of their Supercell album on March 4, 2009. The updated release included the art book originally bundled with the indie version, contained more songs than the original, and included a DVD with music videos for four songs. The album obtained a No. 4 ranking on Oricon's weekly albums chart, and in June 2009 was awarded the Gold Disc by the Recording Industry Association of Japan for having exceeded 100,000 copies shipped in a single year. Ryo approached singer Nagi Yanagi to be the vocalist for Supercell's debut single "Kimi no Shiranai Monogatari" (君の知らない物語), who was known for her uploads to Nico Nico Douga under the name Gazelle. The single was released on August 12, 2009 and ranked No. 5 on Oricon's weekly singles chart. The song "Kimi no Shiranai Monogatari" was used as the ending theme song for the 2009 Bakemonogatari anime series, and the single also included two tracks featured in the 2009 animated film Cencoroll. Supercell was chosen as one of the best five new Japanese artists of 2009 during the 2010 Japan Gold Disc Award competition.

Musical style and influences
Daniel Robson of The Japan Times described Supercell's music as "sentimental J-pop...[that] also explores the genre's jazzier, spunkier and dancier elements." Their sound has been compared to pop singers Aiko and Yui, and Ryo has stated himself that he likes expressing human emotions in his music. When creating a song, Ryo has often hummed a tune into a digital recorder, or starts by playing the piano. While it depends on the song, Ryo has stated he generally "play[s] the piano and take[s] notes of the chord progression" and then writes the lyrics. Ryo has cited "artists that blend rock and hip-hop styles with today's latest technology" as influencing his music, including: Massive Attack, Boom Boom Satellites, Portishead, Tricky, and Unkle.

Ryo found it difficult at first to write "tenderhearted" lyrics for songs meant to be sung by young women. When describing the lyrics for his songs using Hatsune Miku as the vocalist, Ryo felt that writing without hesitation based on his initial ideas with minimal editing was best, because the singer, as a computer program, would not feel embarrassed about singing the lyrics. He admitted that his friends would laugh when he played the songs, but he thought that "if a 16-year-old girl is supposed to be singing...it is best if she sings about romance." When writing lyrics for human singers, Ryo takes more care in writing lyrics that singers would not be embarrassed to sing. When Ryo receives an offer to compose theme music, he writes lyrics that tie in with the theme and mood of the given work, such as the ending themes "Kimi no Shiranai Monogatari" for the anime Bakemonogatari, and "Hoshi ga Matataku Konna Yoru ni" for the visual novel Mahōtsukai no Yoru.
