Drumroll, Please: 'Glass Heart' Teaser Trailer Sets Stage for Heartfelt Musical Odyssey Ahead Of July 31 Premiere
Turn up the volume! The Japanese music drama Glass Heart premieres July 31 - and today, the teaser trailer offers a first look at the electrically charged, heart-thumping sights and sounds of this series. For the first time, fans will hear the song "Crystalline Echo" by the series' band TENBLANK, sung by Takeru Satoh with lyrics by Yojiro Noda of RADWIMPS! In addition, teaser art and character art have been released.
The teaser opens with Naoki Fujitani (Takeru Satoh), the lead vocalist of the four-member band TENBLANK, as the curtain rises on their live performance. The live scene, which involved over 5,000 extras and was shot with 12 cameras, is truly breathtaking, creating a sense of realism and excitement that ranks among the largest in Japanese drama history.
Along with Satoh, the band members - guitarist Sho Takaoka (Keita Machida), keyboardist Kazushi Sakamoto (Jun Shison), and heroine drummer Akane Saijo (Yu Miyazaki) - underwent rigorous musical training to deliver genuine performances.
Glass Heart follows Fujitani's growth as he navigates conflicts with charismatic rival vocalist Toya Shinzaki (Masaki Suda) from the competing band OVER CHROME, while becoming entangled in the schemes of a powerful music industry producer. Throughout these challenges, the band members support each other, deepening their bonds and growing as a destiny-bound unit.
The song "Crystalline Echo," composed by Masahiro Tobinai and written by Yojira Noda, is just one of the several songs Noda pens for TENBLANK featured in this series.
Newly announced cast members include Erika Karata as TENBLANK's manager Miyako Kai, Pistol Takehara as Genji Kamiyama, Akari Takaishi as the diva Yukino Sakurai, who performs songs written by Fujitani, and YOU as Momoko Saijo, Akane's mother and confidante. Naohito Fujiki plays the envious music producer Ichidai Isagi, Takayuki Yamada as the vocalist of the popular rock band Takaoka once belonged to, Reini as Mahiro Arisugawa from OVER CHROME, and Miku Uehara as Akane's friend .
Glass Heart streams on July 31, only on Netflix.
