Risky Melody has built more than 1500 performances over 12 years at live houses across Japan. This work carries all of those unparalleled experiences and is the first release sent toward the "world". Having gained strong responses not only domestically but also overseas, they finally present Risky Melody's rock to the world. This album packages the very time they have walked, as Risky Melody pursues live energy, the reality of the band, and sonic strength that transcends language and borders. The title conveys not only the meaning of challenging the world, but also the determination to expand Risky Melody's own "world" from here. This sound born from Japanese live houses now steps out into the world.
