WU LYF (pronounced "Woo Life", stands for "World Unite Lucifer Youth Foundation") were a band from Manchester, England that originally became known for creating a mystery about themselves by declining requests for interviews and not releasing much information to the press. The band describes their music as "heavy pop". Their manager, Warren Bramley, has previously worked with Tony Wilson at Factory Records. WU LYF formed in the summer of 2008 in Rusholme, Manchester and comprises "Jeau" (Joe Manning), "Lung" (Tom McClung), "Elle Jaie" (Ellery Roberts) and "Evnse" (Evans Kati). The band began on a steady diet of local hardcore music, even starting their own record label titled Ridiculous Records.

Having caught the attention of the UK music industry and press after making a series of early recordings available through their website, WU LYF began a monthly residency, entitled "Play Heavy Pop", at Manchester's An Outlet coffeehouse in December 2009. The band's first gig outside of Manchester came in July 2010 at the MIDI Festival on the French Riviera.

Subsequent shows include France's Transmusicales Festival, Berlin's Transmediale festival and sold-out headline shows in Glasgow and London. In July 2010 the band announced the formation of the Lucifer Youth Foundation, giving new members an illustrated bandit mask and a 12" single featuring the tracks "Concrete Gold" and "Heavy Pop".

The band started recording their debut album in November 2010 using the money generated by the L Y F membership scheme. Deciding against the conventional studio set up, they instead took over Saint Peter's church in Ancoats, Manchester, to record their album.

The album is self-produced. The band declined all offers from established record labels and released their debut album, entitled Go Tell Fire To The Mountain, themselves on 13 June 2011 through the L Y F recordings imprint.

In support of the record's release, the band played several dates in the UK to critical acclaim, culminating in the curation of the Great Bridgwater Street Tunnel as part of the Manchester International Festival.
