Introduction to Big Loud Diamonds

Because the release method of "Sakura no Flower 2008" (桜の花びらたち2008) violated antitrust laws and other issues caused many controversies, the contract between AKB48 and the original record company DefSTAR Records was terminated. In the past 8 months, except for "Baby! Baby! Baby!" which was released as a distributed download, no physical singles were released. Therefore, this is also AKB48’s first single after signing with King Records.

The ACE of SKE48, which was just established at the time, was launched. Jurina Matsui, who was only 11 years old at the time, served as the center of this single and appeared on the cover of the single alone, which caused huge controversy and discussion at the time. . The advertising slogan is "Shout it loudly and you'll become a diamond" (大で声べば、ダイヤモンドになる).

The PV takes the form of a short play. The director is Eiki Takahashi, who directed the PV of "Sakura no Petals 2008".

The shooting was carried out in September 2008 near the entrance of the Bunka Gakuin in Chiyoda-ku, Tokyo, in lecture halls, corridors, classrooms, libraries and other places. A total of 69 members, including graduate students, participated in the PV recording. In addition to SKE48's Jurina Matsui, some women from the surrounding area also participated in the filming as spectators.

The scene is set in the cultural festival (culture festival) of the fictional high school "Matsuoka Girls' High School", where AKB48 plays the role of "the female high school student who plays AKB48". The plot is set as a second-year class B student (Jurina Matsui) who is recruiting volunteers in school to sing "Diamond Loud" at a cultural festival. The students who were summoned watched the AKB video and began to practice independently. However, the team member (Atsuko Maeda) who was supposed to be the center of the performance was unwilling to practice because he had been worried about the university entrance exam, so he clashed with the captain (Miyazawa Sae). On the day of the official performance, Maeda did not show up, so Matsui had to stand in the center for Maeda. Maeda, who was alone, received text messages of encouragement from his partners, and finally ran back to the venue and rushed to the stage near the end of the performance, completing a perfect performance together.

The scene of the conflict between Maeda and Miyazawa was not included in the scripts sent to other members. In addition to this scene, the two people's scripts also included the words "cannot be included" written by the director. Tell other members about this."

This work peaked at No. 3 on the Oricon Weekly Singles Chart, surpassing "BINGO!", "My Sun" (Servant of the Sun) and "Romantic, No Need" (ロマンス, イラネ) three games set a record of 6th place.

The loud "ダイヤモンド" text printed on the cover and other places was written by Erina Ono, who was part of Team K at the time.

Minami Takahashi, a veteran member of AKB48, said, "From about this song on, I really feel that our supporters are getting more and more."

The lyrics of this work also exist in English. This English lyrics was used in overseas performances such as Japan Expo 2009 in Paris, NEW YORK ANIME FESTIVAL, and Cannes mipcom.

The lead singer of the English version is Saiga Akimoto, who is better at English among the members. The members who were scheduled to participate in the performance were not told until a week ago that "if they can't sing the entire song in English, they can't go (to the performance)" and they conducted emergency practice. There are also members of the selection team who cannot do it because they have not participated in overseas performances.

In addition, the name that Matsui Jurina calls out on the cover is "Mariko sama!" (See Ariyoshi*** and Kuniko Mariko's birthday celebration chapter) The release time of this song is BayFM broadcast on September 15th Special program "Holiday Special bayfm meets AKB48 3rd Stage?REAL?". But for unknown reasons, in the early morning of September 9th, the song before the arrangement of this work was circulated to the Internet. AKS stated on its official blog that it would take legal measures [8], but did not announce any subsequent progress.

In addition, this incident was later reported by the concert "AKB48. Could it be that the sound source of this concert will not be leaked?" (AKB48 まさか、このコンサートの音源は流しないよね?).
