With "Yellow Moonlight", which was a track on Okayasu's first album "Yume e no Setsuzokushi"（夢への接続詩...Dream Connection）, Nishimatsu managed to make a hybrid of those styles that were present from both albums. Beginning with some techno jazz swing, the keyboards then enter the dance floor with a mellow urban contemporary melody, and the two just weave in and out with each other in a pleasant little dance that also include that wailing guitar of early City Pop. Okayasu herself was responsible for the lyrics.
Matt also let me know that he didn't know anything about the singer outside of the fact that "Yellow Moonlight" was a Nishimatsu composition. I didn't know anything about her either but she does have a J-Wiki article, so I was able to glean the following information. Born in Tokyo, she graduated from the Joshibi University of Art and Design, and is a singer, actress and car racer. Beginning her career in show business as a member of a street performance team, she became a host of the late-night TV show "All-Night Fuji", and then went into acting and singing. She started auto racing from the 1990s and is currently the director behind her own team, Heart-in-Heart Racing Team. As for music, she released a total of 3 albums and 2 singles up to 1987.
The video below has her in a commercial for a Subaru.
