[Machine Translation] Masako-san, a legendary six-member girl band active from the end of the 1980s to the beginning of the 1990s, is releasing a CD of sound recordings from the time of their activities. Masako-san was formed in 1986 by the sisters Mayutan and Sabrina. The single cut this time is "10cm no Whale" from the album "MONKEYS WAX," which was independently released through the Ikaten label and Nagomu Records, with Sabrina in charge of the lyrics and composition.
