Fabio and Grooverider began playing house at Mendoza's in Brixton. From there the pair went on to a venue in Barrington Road in Brixton, but it was not until 1991 that they would really make their mark.
That year, Grooverider and Fabio took up a residency at Rage. Throughout the 1990s, Grooverider released tracks as Codename John and helped build the reputations of Matrix and Boymerang with releases on his own record label, Prototype.
