LFO

LFO is a Leeds-based English electronic group formed in 1988 by Mark Bell and Gez Varley, whose name comes from the term low frequency oscillator, a synthesizer and sampler component used to alter sound. The duo are associated with bleep techno, electronic, electronica, IDM and techno, and are regarded as pioneers of early 1990s bleep techno.

Early work and Warp Records

Bell and Varley meet while studying in Leeds. Their first track, “LFO”, goes to Nightmares On Wax as a demo, and its club popularity leads to a Warp release in 1990. The single reaches the UK Top Twenty and helps establish the group’s profile on Warp, a label they remain closely associated with.

Their debut album, Frequencies, includes “LFO” and the follow-up single “We Are Back”. It becomes an important release for Warp Records and is issued with a warning sticker about the strength of its low-frequency bass signals and possible damage to speakers.

Line-up changes and later releases

Varley leaves the duo in 1996 and continues with a solo career. Bell carries on recording both under his own name and as LFO, and also produces albums for Björk and Depeche Mode. LFO later release Advance, followed in 2003 by Sheath, which returns to the more minimal techno approach of their early work.

Activity after the original period

The group’s active period runs until 2014. They briefly reunite in 2009, announce new activity and a track called “Summer of My Life”, and then break up again later that year.

Associated acts and recognition

LFO’s rise is closely linked to fellow Warp artists including Nightmares On Wax and Sweet Exorcist. Their work also helps demonstrate Warp’s growth as a successful independent electronic label.

In the United States, another group also uses the name LFO, but the English act remains the Leeds electronic duo associated with “Low Frequency Oscillator”.
