UK Hard Dance act. Adam and Les formed Lab 4 in 1994 and soon secured début gigs at fetish night Torture Garden and then Club UK in Wandsworth, London. In the late 90's regular PA's at trance club nights such as Escape From Samsara in Brixton, London, brought them greater recognition. Into the 21st century they grew to become the biggest live Hard Dance act in the UK with regular gigs overseas and subsequently gained a large and loyal following from fans across the globe.

In September 2006 the duo announced that it was time to call it a day with Lab 4 and arranged a series of farewell gigs up to and including New Year's Eve 2006-07.
