Side 2, however, due to the duo's running out of money for studio time, was a bizarre, abstract collision of previously recorded music being looped, repeated, mangled, and played at incorrect speeds — the first rock remix, perhaps, or an early example of plunderphonics.

The project, a compact disc recording called Plunderphonic, featured Oswald's manipulations of familiar recordings by artists such as Michael Jackson, Glenn Gould, Dolly Parton, and Elvis Presley. By using a variety of recording techniques, including electronic sampling and tape manipulation, Oswald created new, often radically different compositions from the existing material.
This word (actually, plunderphonic) was coined by musician John Oswald and used as the title of a CD he released in 1989.
