Logic System, the unit led by Hideki Matsutake, who rose to fame as YMO's programmer, released their first album in '81. This album, with its prominent electronic sound, seemingly quenched the thirst of fans of YMO's "BGM," which was released around the same time and featured less frequent use of synthesizers. It's a classic known to be a favorite of Danielle Bardelli and DJ Harvey.
