Double Negative is a piece of land art located in the Moapa Valley on Mormon Mesa (or Virgin River Mesa) near Overton, Nevada. Double Negative was completed in 1970 by the artist Michael Heizer.

The work consists of a long trench in the earth, 30 feet (9 m) wide, deep, and 1500 feet (457 m) long, created by the displacement of 244,000 tons of rock, mostly rhyolite and sandstone. Two trenches straddle either side of a natural canyon (into which the excavated material was dumped). The "negative" in the title thus refers in part to both the natural and man-made negative space that constitutes the work. The work essentially consists of what is not there, what has been displaced.

In 1969 the art dealer Virginia Dwan funded the purchase of the 60-acre site for Double Negative and in turn the artist transferred the property deeds to Dwan. In 1971 Heizer prevented the Dwan Gallery from selling the work. Dwan then donated Double Negative to the Museum of Contemporary Art, Los Angeles (MoCA) in 1984, with Heizer’s blessing, to coincide with “In Context: Michael Heizer, Geometric Extraction”. Among the terms of the agreement with the museum is the fact that, according to the artist's wishes, MoCA will undertake no conservation of the piece as Heizer wants nature to eventually reclaim the land through weather and erosion.

For the solo exhibition "In Context: Michael Heizer, Geometric Extraction", MoCA was able to include a photographic panorama of Heizer’s work. For the large-scale, historical survey of land art “Ends of the Earth” at MoCA in 2012, Heizer did not want any representation of Double Negative to be included in the exhibition. A good aerial photograph appears in the informative catalog, but Heizer reportedly worried that documentation in a museum gallery misrepresents sculpture that can be known only through physical experience.

The work is currently owned by MoCA and is accessible by four-wheel drive vehicle or motorcycle.

Double Negative was an all-star hardcore band from Raleigh, North Carolina. Guitarist Scott Williams (aka: Epic Warfare) previously played in American Lore (with Mike Dean from Corrosion of Conformity), Fight 4 Life, Second Coming, Days Of..., Dixie Automotive, Garbageman, Daddy and Volcanoes (band). Original drummer Brian Walsby had been in California's Scared Straight, Willard, Shiny Beast and Patty Duke Syndrome (with Ryan Adams), as well as Wwax, Daddy, Siberian, Snake Nation (with Mike Dean and Woody Weatherman of C.O.C.) and even the final Polvo line-up that recorded Shapes before they disbanded. Original singer Kevin Collins (aka: KC) was in Subculture, Days Of and Erectus Monotone. Bassist Justin Gray was in Dixie Automotive, Big Dan, Willard, Garbageman, The Rails, and The Step Gods.

In 2011, both Brian and Kevin left the band for personal reasons. Charlotte, NC native Booby Michaud (GRIDS, Brain F≠, Infeccion) was asked to play drums and Cameron Craig (Logic Problem, Shards, Atrophix) took over vocal duties.

Their debut release The Wonderful and Frightening World of... LP came out on No Way Records in 2007. The 3-song Raw Energy EP was released in 2008. A burglarized practice space in December 2009 delayed their next release when a 16-track portable Korg was stolen containing the almost-complete LP. The band was finally able to deliver their sophomore release Daydreamnation, on July 27, 2010.

They played the "Hidden World" fest in Toronto, Canada in October 2007, and had an 8-page feature interview in the August 2008 edition of Maximumrocknroll (issue No. 303). In September 2010 they toured Europe for a handful of dates, supporting their Daydreamnation LP.

In 2012, the band played Austin, TX's Chaos in Tejas festival, completed a full US summer tour, opened for Off! and Negative Approach on a two-week stretch of dates, and are slotted to continue as support for Off! and The Spits this Fall.
