I find that this album, has a mid-late sixties pop feel that was so refreshing when released it still is crisp and crackly like a candy wrapper even today. The songs are sung in Japanese and English, the phonemes being more important than full meaning of the lyrics most of the time.
Peppy and properly pizzicato in tempo, the music is very electronic, the singing breathy in contrast. The lyrics, presented inside, somewhat clarify the meaning, but I believe are meant to be experienced as a Gestaltian whole, sound, sound and sound altogether in motion.
It's Catchy, you'll like it.
