together, the groups ended up recording a track each, then exchanging them to the other for additional input. Colourbox came up with "Pump Up the Volume", a percussion-led near-instrumental, featuring an Eric B. & Rakim sample that gave it its title, while A.R. Kane created the more deliberately arty "Anitina (The First Time I See She Dance)" in another studio. Colourbox then added a heavy drum-machine rhythm and effects to "Anitina" and A.R. Kane overdubbed some additional guitar to "Pump Up the Volume". The coup de grace, however, was the addition of scratch mix effects and samples by DJs Chris "C.J." Mackintosh and Dave Dorrell. Colourbox told Watts-Russell that they didn't want "Anitina" on the B-side and wanted "Pump Up the Volume" released solely as a Colourbox track. Watts-Russell overruled them, in part because of Young's notoriously slow work rate with the prospect of the track being held up for another 12 to 18 months, and released the track as M|A|R|R|S as originally planned. This led to the relationship with the band collapsing, and they never recorded for 4AD again. The two tracks were released to United Kingdom dance clubs in July 1987, on an anonymous white label with no artist credit. "Pump Up the Volume" proved to be the more popular side and was the track more heavily promoted. 4AD released the 12" single (as, officially, a double A-side) on 24 August of that year. It entered the UK Singles Chart the following week at number 35, a strong initial showing for an unknown act, especially with 12" sales. However, what gave "Pump Up the Volume" its commercial edge was the remix released a week later. This remix became the best-known version of the track, transforming it by the addition of numerous samples that provided the record with additional hooks besides its oft-repeated title chant, such as those of tracks by Public Enemy, Criminal Element Orchestra and the Bar-Kays. It was this remix, rather than the original, that was edited down to create the 7-inch version of the track, which began picking up radio play. As the record climbed the charts, the single ran into legal difficulties. With "Pump Up the Volume" standing at number two, an injunction was obtained against it by pop music producers Stock Aitken Waterman (SAW), who objected to the use of a sample from their hit single "Roadblock". Distribution was held up for several
