London Underground has been connected with the beginning of On-U Sound label. Their "Learn A Language" track was the B-side of On-U's debut release, a split 7'' single with New Age Steppers ("Fade Away" / "Learn A Language"). The band, active the first half of the decade, developed a kind of white reggae-dub sound with influences from the avant-funk and alternative-dance air of post-punk era. Constant members were Martin Frederix (bass, guitar, vocals), Dan Sheals(drums), Kendall Ernest (bass) and On-U cofounder Pete Holdsworth (vocals), who later involved with reggae labels 'Pressure Sounds' and 'Green Tea'.
Following their second single "Train Of Thought" (1981), the three-track 10'' EP "Watching West Indians In The Cold", (fourth in the "On-U Disco Plates" series) is the step forward for the band ,as well the predecessor of their 1983 releases, "At Home With London Underground" (LP) , "Current Affairs Session" (mini-LP) and "Between The Lines" (7" single), which consist the main works of London Underground and also the last, as the band finished soon after.
