BACK-ON, one of the most popular Japanese rock bands overseas, will celebrate their 15th anniversary with self-cover best album FLIP SOUND, out digitally on 17 February worldwide. A special two-disc international edition of the album will be released from London's JPU Records in April, boasting lyric translations, transliterations and content from BACK-ON available on a physical format for the first time.

FLIP SOUND will feature 15 of BACK-ON's biggest and most recognised global hits re-recorded, giving new and old fans the chance to hear classic tunes reborn with a modern edge. It will include their anime anthem STRIKE BACK, which has been streamed over 11 million times on Spotify and featured as the theme song to popular animated series Fairy Tail. It will also include tracks used in Japan's iconic Gundam franchise, and their songs from video games, such asTales of the World: Radiant Mythology 2 on PlayStation Portable.

Vocalist and guitarist KENJI03 comments, "BACK-ON celebrated our 15th anniversary in October last year, and now we are excited to release this collection of newly arranged self-covers of songs from our back catalogue that we have played live around the world! Once things return to normal, we can't wait to get back on the road and see everyone – until then, we hope you’ll enjoy this album, and let's all get through this together!"

Rapper TEEDA states, "While we're excited to release this 15th anniversary album FLIP SOUND, I'm so sorry that we cannot perform these updated versions of our songs live for our fans around the world. But this situation will end eventually – and when it does, we'll be right there, so please wait for us!"

BACK-ON have performed on stages across Asia, Europe and the Americas. Due to their popularity around the world, some of their prior releases have included vocals entirely in other languages, pushing boundaries even further for music from Japan. When not writing their own material, KENJI03 can be found penning hits for other artists and media (such as songs for Japanese pop diva KODA KUMI, K-pop stars TVXQ, and for games on the Nintendo 3DS), while TEEDA recently began his solo rap project.

This is Japanese positive rock energy, fuelled by anime spirit, hip hop flavours and pop-punk power.
