Discovering the hidden pages of J-pop mainstay Yumi Matsutoya’s prolific songbook is supremely rewarding. ’70s folk trends inspire the wistful, woodwind-laden reverie of “Erigeron Philadelphicus, Erigeron Annuus”, while “Cloudy Weather / Kumori Zora” drifts into laidback jazz fusion, “Cobalt Hour” flirts with cosmic funk and “Autumn Park” evokes pure synth-driven '80s nostalgia.
