Acid Brass began in 1997 as a collaboration between Deller, the
Stockport-based Fairey Brass Band and
Rodney Newton who created all the brass arrangements. Deller saw a connection between the two apparently disparate genres, viewing them as "two authentic forms of folk art rooted in specific communities". The music has since been taken all over the world, and was performed by the Fairey Band before a London crowd of 25,000 in July 2005. In 1997,
The KLF co-founder
Bill Drummond heard Acid Brass performing The KLF's "
What Time Is Love?" as part of their encore. Consequently, Acid Brass collaborated with The KLF (appearing in their alternative personae as The Justified Ancients of Mu-Mu) on a track titled "
Fuck the Millennium", incorporating Acid Brass' cover of "What Time Is Love?". The track was released as a single under the moniker
2K. The track "The Groove that won't stop" was played over the end titles to the 2010 movie "
Four Lions". The Fairey Band still plays regular Acid Brass gigs at major music festivals in the UK and abroad, and in 2011 issued a new Acid Brass CD. In June 2024, Deller brought Acid Brass to the streets of
Melbourne, as part of the 2024
RISING: festival, with local brass bands including Merri-bek City Band, Glenferrie Brass, Victorian State Youth Brass Band, Dandenong Band, and Western Brass. ==Albums==
