From releasing three brand-new tracks to touring across their own country with the title in blind sight, Japanese band coldrain have kept anticipation high. Now, the quintet has finally unveiled their new EP “OPTIMIZE” – a 5-track release delivering the band’s very own message against a polished and streamlined world. A message for living not as someone’ s copy, but as one’ s true self – imperfect, unfiltered, and alive. Written by the members Y.K.C and Masato, mixed by Sam Guaiana and mastered by Mike Kalajian, “OPTIMIZE” delivers an emotion filled experience, charged with energy across genres. The EP includes the band’s latest single releases “INCOMPLETE”, “CHASING SHADOWS”, and “FREE FALL”.
