Having just released a self-titled debut full-length last month, Tokyo’s Once Grace Forever wasted no time in putting out its follow-up single “♭1”. The single’s A-side, “Ao” is the more impressive track of the two, transitioning back and forth well between clean lulls and big, wailing choruses. “Flat” is a fuzzy guitar pop tune that doesn’t change much dynamically, relying instead on the vocal melody and melancholic chord progressions. The single is pretty solid, but might have come out a little too soon after the record, which is a tough act to follow. If you haven’t heard any of Once Grace Forever’s music, I recommend starting here and then moving on to the album.
