Some context: The Blackfoot Confederacy, Niitsitapi or Siksikaitsitapi (nitmowmeko, meaning "the people" or "Blackfoot-speaking real people") is a historic collective name for the four bands that make up the Blackfoot or Blackfeet people: three First Nation band governments in the provinces of Saskatchewan, Alberta, and British Columbia, and one federally recognized Native American tribe in Montana, United States. The Siksika ("Blackfoot"), the Kainai or Kainah ("Blood"), and the Northern Piegan or Peigan or Piikani ("Apa'tosee" or "Poor Robes") reside in Canada; the Southern Piegan/Piegan Blackfeet ("Amskapi Piikani" or Pikuni) are located in the United States, where they are also known as the Blackfeet Nation. In modern use, the term is sometimes used only for the three First Nations in Canada. Historically, the member peoples of the Confederacy were nomadic bison hunters and trout fishermen, who ranged across large areas of the northern Great Plains of western North America, specifically the semi-arid shortgrass prairie ecological region.
The Niitsitapi main source of food on the plains was the American bison (buffalo), the largest mammal in North America, standing about 6 1/2 feet (2.0 m) tall and weighing up to 2,000 pounds (910 kg). Before the introduction of horses, the Niitsitapi needed other ways to get in range. The buffalo jump was one of the most common ways. The hunters would round up the buffalo into V-shaped pens, and drive them over a cliff (they hunted pronghorn antelopes in the same way). Afterwords the hunters would go to the bottom and take as much meat as they could carry back to camp. They also used camouflage for hunting. The hunters would take buffalo skins from previous hunting trips and drape them over their bodies to blend in and mask their scent. By subtle moves, the hunters could get close to the herd. When close enough, the hunters would attack with arrows or spears to kill wounded animals. The people used virtually all parts of the body and skin. The women prepared the meat for food: by boiling, roasting or drying for jerky. This processed it to last a long time without spoiling, and they depended on bison meat to get through the winters. The winters were long, harsh, and cold due to the lack of trees in the Plains, so people stockpiled meat in summer. As a ritual, hunters often ate the bison heart minutes after the kill. The women tanned and prepared the skins to cover the tepees. These were made of log poles, with the skins draped over it. The tepee remained warm in the winter and cool in the summer, and was a great shield against the wind. The women also made clothing from the skins, such as robes and moccasins, and made soap from the fat. Both men and women made utensils, sewing needles and tools from the bones, using tendon for fastening and binding. The stomach and bladder were cleaned and prepared for use for storing liquids. Dried bison dung was fuel for the fires. The Niitsitapi considered the animal sacred and integral to their lives.

Some context: Polly Jean Harvey was born on 9 October 1969 in Bridport, Dorset, the second child of Ray and Eva Harvey, who owned a stone quarrying business, and grew up on the family's farm in Corscombe. During her childhood, she attended school in nearby Beaminster, where she received guitar lessons from folk singer-songwriter Steve Knightley, and her parents introduced her to music that would later influence her work, including blues music, Captain Beefheart and Bob Dylan. Her parents were avid music fans and regularly arranged get-togethers and small gigs; among their oldest friends was Ian Stewart. As a teenager, Harvey began learning saxophone and joined an eight-piece instrumental group Bologne, based in Dorset.
As Harvey embarked on her solo career, she explored collaborations with other musicians. In 1995 she released her third studio album, To Bring You My Love, featuring former bandmate John Parish, Bad Seeds multi-instrumentalist Mick Harvey and French drummer Jean-Marc Butty, all of whom would continue to perform and record with Harvey throughout her career. The album was also her first material to be produced by Flood. Simultaneously a more blues-influenced and more futuristic record than its predecessors, To Bring You My Love showcased Harvey broadening her musical style to include strings, organs and synthesisers. Rolling Stone said in its review that "Harvey sings the blues like Nick Cave sings gospel: with more distortion, sex and murder than you remember. To Bring You My Love was a towering goth version of grunge." During the successive tours for the album, Harvey also experimented with her image and stage persona. The record generated a surprise modern rock radio hit in the United States with its lead single, "Down by the Water." Three consecutive singles -- "C'mon Billy", "Send His Love to Me" and "Long Snake Moan" -- were also moderately successful. The album was a commercial success selling one million copies worldwide including 370,000 in the United States. It was also certified Silver in the United Kingdom within seven months of its release, having sold over 60,000 copies. In the United States, the album was voted Album of the Year by The Village Voice, Rolling Stone, USA Today, People, The New York Times and the Los Angeles Times. Rolling Stone also named Harvey 1995's Artist of the Year and Spin ranked the album third in The 90 Greatest Albums of the '90s, behind Nirvana's Nevermind (1991) and Public Enemy's Fear of a Black Planet (1990). In 1996, following the international success of To Bring You My Love and other collaborations, Harvey began composing material that would end up on her fourth studio album, during what she referred to as "an incredibly low patch." The material diverged significantly from her former work and introduced electronica elements into her song-writing. During recording sessions in 1997 original PJ Harvey Trio drummer Rob Ellis rejoined Harvey's band, and Flood was hired again as producer. The sessions, which continued into April the following year, resulted in Is This Desire? (1998). Though originally released to mixed reviews in September 1998, the album was a success and received a Grammy Award nomination for Best Alternative Music Performance. The album's lead single, "A Perfect Day Elise," was moderately successful in the United Kingdom, peaking at number 25 on the UK Singles Chart, her most successful single to date.
