Plunderphonics is a term coined by composer John Oswald in 1985 in his essay Plunderphonics, or Audio Piracy as a Compositional Prerogative. It has since been applied to any music made by taking one or more existing audio recordings and altering them in some way to make a new composition. Plunderphonics can be considered a form of sound collage.

Although the concept of plunderphonics is seemingly broad, in practice there are many common themes used in what is normally called plunderphonic music. This includes heavy sampling of educational films of the 1950s, news reports, radio shows, or anything with trained vocal announcers. Oswald's contributions to this genre rarely used these materials, the exception being his rap-like 1975 track "Power."

The process of Sampling other sources is found in various genres (notably hip-hop and especially turntablism), but in plunderphonic works the sampled material is often the only sound used. These samples are usually uncleared, and sometimes result in legal action being taken due to copyright infringement. Some plunderphonic artists use their work to protest what they consider to be overly-restrictive copyright laws. Many plunderphonic artists claim their use of other artists' materials falls under the fair use doctrine.

James Marshall "Jimi" Hendrix (born Johnny Allen Hendrix; November 27, 1942 – September 18, 1970) was an American musician and singer-songwriter. He is widely considered to be the greatest electric guitarist in music history, and one of the most influential musicians of his era despite mainstream exposure limited to just three years. After initial success in Europe with his group The Jimi Hendrix Experience, he achieved fame in the United States following his 1967 performance at the Monterey Pop Festival. Later, he headlined the iconic 1969 Woodstock Festival and the 1970 Isle of Wight Festival. He often favored raw overdriven amplifiers with high gain and treble and helped develop the previously undesirable technique of guitar amplifier feedback.

Hendrix helped to popularize use of the wah-wah pedal in mainstream rock, which he often used to deliver tonal exaggerations in his solos, particularly with high bends, complex guitar playing, and use of legato. As a record producer, he also broke new ground in using the recording studio as an extension of his musical ideas. He was one of the first to experiment with stereophonic phasing effects for rock recording.^{[citation needed]} He was influenced by blues artists such as B.B. King, Muddy Waters, Howlin' Wolf, Albert King and Elmore James,rhythm and blues and soul guitarists Curtis Mayfield and Steve Cropper, and the jazz guitarist Wes Montgomery. Hendrix began dressing and wearing a moustache like Little Richard when he performed and recorded in his band from March 1, 1964 through to the spring of 1965. In 1966, he stated, "I want to do with my guitar what Little Richard does with his voice".
