This is actually her latter album released in 1977. Her earlier album consist of mostly Folk Music before gradually transiting to the Japanese New Music genre on this album. One of the earlier City Pop style album as well, beautifully convey by the A-B side naming of Sun-Light side and Moon-Light side. Really pretty cover art as well! Available in excellent mint condition!
