Although they spent only a brief period on 4AD, A.R. Kane had a hand in the most freakish success in the label's history. The studio-based outfit comprised East London duo Alex Ayuli and Rudi Tambala, who described their music as "dreampop". After releasing their debut EP on the One Little Indian label, they moved to 4AD in 1987 and issued the Lollita 12", which was produced by Robin Guthrie of the Cocteau Twins. Alex and Rudi then left for Rough Trade.
During their brief stint on 4AD, A.R. Kane had taken up Ivo's suggestion that they collaborate with labelmates Colourbox. The session produced a sample-heavy dance track titled 'Pump Up The Volume', which was released under the name M|A|R|R|S and astounded all concerned by reaching number one in the UK charts. It remains the biggest single in 4AD's history.
