sampling 

Variations is a series history of appropriative collage in music, compositions made using recordings of older ones. It's a practice that in the '80s became known sampling — after the digital sampler — a breakthrough instrument which was designed to mimic traditional musical instruments by allowing the player to trigger recordings of them back on a keyboard. But it didn't take long for musicians to realize that the true strength of the sampler was the way in which it made it easy easy to collage and manipulate the best sounds from their favorite records into new pieces of music. This practice entered the popular mainstream by the 80s, long after observers had already identified collage as the defining new art form of the 20th century — and the roots of this music go back just as far. Over the course of this series, Leidecker looks at these roots, as appropriative collage developed across experimental and mainstream paths.
