Young formed Colourbox in 1982 with his brother Martyn, and they were joined a year later by vocalist Lorita Grahame. Following their debut single “Breakdown”/”Tarantula” (and a remake with Grahame), the group released one EP and one LP, both self-titled, before teaming up with duo A.R. Kane under the name M/A/R/R/S in 1987. The groundbreaking a-side of the collaboration’s sole single, “Pump Up The Volume,” became a worldwide hit, earning them a Grammy nomination for Best Pop Instrumental Performance in 1989. In 2012, 4AD celebrated Colourbox’s 30th anniversary with a comprehensive retrospective box set.
