LFO is an English techno act on the Warp Records label. LFO were pioneers of the bass-heavy techno music of the late 1980s to mid-1990s. Originally, the group was comprised of Gez Varley and Mark Bell. LFO is now Bell alone.
Their follow-up single, "We Are Back", was released in the summer of 1991.
DJ Martin (Martin Williams) is credited as a cowriter and coproducer of the track "LFO" but was not a member of the group. Mark Bell explains:
"We gave a tape of our recordings to DJ Martin who helped loads with arranging our tracks so it'd work on the dancefloor. We'd just been messing around with drum machines since we were like thirteen, tapping away at them like they were arcade games, making tapes to play our mates at school. Anyway, DJ Martin would play our cassettes in his sets and people would go mental - in a good way - cos they were totally raw.
Varley left in 1996 and formed Feedback with Simon Hartley (a.k.a. Wild Planet). Mark Bell produced Homogenic with Björk and Exciter with Depeche Mode. Bell performed with Björk during her 2007 Volta tour.
The song "Freak" was used in the 2005 film Hard Candy.
