Soft Cell put the synths in northern soul on 5 September 1981, when they took ‘Tainted Love’ to the top of the UK charts.
Soft Cell masterminds Dave Ball and Marc Almond look back on the “enjoyable chaos” of Britain’s first ever synth-pop duo.
The new track is the 'Hallowe'en' Mix of the duo's intense 1983 hit.
'Northern Lights' and 'Guilty ('Cos I Say So)' are the duo's first new songs since 2002.
The multi-disc box encompasses both phases of Soft Cell's career from 1978 to 1984, and the 2001-3 reunion.
