Colourbox were a London-based (Edinburgh born) electronic outfit on the 4AD record label in the 1980s. They produced an electronically-based reggae and soul-influenced pop music, making remarkable use of the technology they had access to at the time. They released a number of records from 1982 until 1987. The band was formed by brothers Martyn Young and Steve Young, with guest singers until Lorita Grahame joined as a permanent member in 1983.

The band had an international hit in 1987 with "Pump Up The Volume", a collaboration with the band A R Kane under the name M|A|R|R|S. The song was notable for being constructed almost entirely from samples of other records, a novel thing for a popular record at that time. The pressures of sudden success and the long running litigation caused by the use of samples ended up causing Colourbox to never to record again. Read more on Last.fm.
