The band recorded their follow up album, Humanication, in 1984 as a planned 1985 release. The first single was "How Much Longer," which had an environmentalist message and featured Sting on backing vocals. The song was released in Germany, but the record label did not like the political nature of the song/album and killed the project. To this day, the album has never been released, although there are apparently bootleg copies in existence. Re-Flex released two songs for the Superman IV soundtrack in 1987, but did not release another album (in the 1980s, at least).
Cool trivia fact #2: An early version of Re-Flex featured Phil Gould and Mark King who would go on to form ... Level 42. Gould, by the way, also played with M ("Pop Muzik").
