Japanese quartet One Eye Closed aren't ones to pigeonhole themselves, blending rock, metal and pop with Vocaloid, hip-hop and jazz to create their own unique sound. Latest single 'Squall', which features guest vocals from AJ Rebollo of ISSUES, is what they describe as their "best mixture of western and eastern music elements," and was written at a time when the band were trying to find themselves. We caught up with vocalist REI to discuss the writing process of 'Squall', its theme and stories from behind the scenes.
