Get ready to turn up the volume on July 31! The Japanese music drama Glass Heart has unveiled its main trailer today, offering viewers their first listen to the title song Glass Heart, written and composed by Yojiro Noda and performed by Takeru Satoh. Crafted to fulfill the production team's request for a sound like never before, the song highlights Noda's distinctive sound.
Not only does Glass Heart feature an all-star cast that includes some of Japan's most prominent actors today - such as Takeru Satoh, Yu Miyazaki, Keita Machida, Jun Shison, and Masaki Suda - it's also generating huge buzz for its unprecedented scale, with the actors dedicating over a year to learning instruments, singing, and even making their actual debut as a band. In the first half of the trailer, the exhilarating melody of "Crystalline Echo captures the characters' rapid rise to stardom. The latter half, set to the newly revealed song Glass Heart, depicts the beginnings of friendship, jealousy, and romance. Viewers will also be mesmerized by one of the largest live performance scenes ever depicted in the history of Japanese drama, presented on a breathtakingly grand scale.
The original score was composed by Masakatsu Takagi, known for his work on many films and TV dramas such as Wolf Children and various commercial scores.
In addition to Yojiro Noda, a diverse and stellar lineup of leading musicians from Japan's current music scene - including Taka (ONE OK ROCK), Yohei Kawakami [Alexandros], Ryujin Kiyoshi, Yaffle, TeddyLoid, and Tanaka - have contributed songs. Next-generation vocalists gaining popularity among young audiences, such as Zarame and ao, are participating as well, bringing the total number of distinguished artists involved to 26.
Catch an unforgettable journey into the world of dreams and ambition with Glass Heart, streaming on July 31, only on Netflix.
Story Akane Saijo, a drummer who was ousted from her previous band just before her debut, is unexpectedly chosen by Naoki Fujitani - a reclusive and brilliant musician - to join his new band, TENBLANK. Together with band members Sho Takaoka and Kazushi Sakamoto, the band gains fame through Fujitanis distinctive compositions and their electrifying performances. As TENBLANK rises to stardom, they face numerous challenges, and Akanes journey from obscurity to stardom unfolds as Fujitanis secrets emerge. Will the band withstand the storm, and where will Akanes heart lead her?
