2022 reissue, first time on vinyl! In complete honesty Ultra blue's sound isn't greatly removed from that of the album that came before: Deep river. There is a stronger emphasis on synthesised sounds on some of the albums cuts. But overall the sound and tone of the songs is similar: tittering between jubilant playfulness, and poignant emotion. If anything, half of the album sounds like it was recorded around the same time as Deep river. The more stripped down songs such as "Dareka no negai ga kanau koro", "Colors" and "Be my last" certainly wouldn't have sounded out of place on Hikaru's last album. It's the synth pop tracks that really do lift this album and help it stand out from Deep river. Ultra blue's sound has enough newness to it that long term fans will love it and hear the evolution of Hikaru's sound, but it's not so new that Hikaru is likely to win over those who weren't sold on her previous effort.
