In music, sampling is the act of taking a portion, or sample, of one sound recording and reusing it as an instrument or a sound recording in a different song or piece. Sampling was originally developed by experimental musicians working with musique concrete and electroacoustic music, who physically manipulated tape loops or vinyl records on a phonograph. By the late 1960s, the use of tape loop sampling influenced the development of minimalist music and the production of psychedelic rock and jazz fusion. Hip hop music was the first popular music genre based on the art of sampling - being born from 1970s DJs who experimented with manipulating vinyl on two turntables and an audio mixer.
Spoken word
Usually taken from movies, television, or other non-musical media, spoken word samples are often used to create atmosphere, to set a mood, or even comic effect. The American composer Steve Reich used samples from interviews with Holocaust survivors as a source for the melodies on the 1988 album Different Trains, performed by the Kronos Quartet.  Many genres utilize sampling of spoken word to induce a mood, and Goa trance often employs samples of people speaking about the use of psychoactives, spirituality, or science fiction themes. Industrial is known for samples from horror/sci-fi movies, news broadcasts, propaganda reels, and speeches by political figures. The band Ministry frequently samples George W. Bush. Paul Hardcastle used recordings of a news reporter, as well as a soldier and ambient noise of a protest, in his single "Nineteen," a song about Vietnam war veterans and Posttraumatic stress disorder. The band Negativland samples from practically every form of popular media, ranging from infomercials to children's records. In the song "Civil War", Guns N' Roses samples from the 1967 film Cool Hand Luke, on the album Use Your Illusion II. Sludge band Dystopia make frequent use of samples, including news clips and recordings of junkies to create a bleak and nihilistic atmosphere.  Other bands that frequently used samples in their work are noise rockers Steel Pole Bath Tub and death metal band Skinless. The extreme metal band Mortician makes extensive usage of horror movie samples, which can sometimes be longer than the actual song itself. The American rapper and producer MF Doom frequently uses spoken word samples, taken from anything from old Spider-Man and Fantastic Four cartoons to Charles Bukowski's "Dinosauria, We" poem. Oasis used a clip from a John Lennon interview for their song "I'm Outta Time". Living Colour samples Malcolm X, John F. Kennedy, and Franklin D. Roosevelt in "Cult of Personality".
