Extended mix

A remix is a piece of media which has been altered from its original state by adding, removing, and/or changing pieces of the item. A song, piece of artwork, book, video, or photograph can all be remixes. The only characteristic of a remix is that it appropriates and changes other materials to create something new.

Most commonly, remixes are a subset of audio mixing in music and song recordings. Songs may be remixed for a variety of reasons:

Remixes should not be confused with edits, which usually involve shortening a final stereo master for marketing or broadcasting purposes. Another distinction should be made between a remix, which recombines audio pieces from a recording to create an altered version of a song, and a cover: a re-recording of someone else' song like Mike D's remix of Moby's Natural Blues.

Since the beginnings of recorded sound in the late 19th century, technology has enabled people to rearrange the normal listening experience. With the advent of easily editable magnetic tape in the 1940s and 1950s and the subsequent development of multitrack recording, such alterations became more common. In those decades the experimental genre of musique concrète used tape manipulation to create sound compositions. Less artistically lofty edits produced medleys or novelty recordings of various types.

Modern remixing had its roots in the dance hall culture of late-1960s/early-1970s Jamaica. The fluid evolution of music that encompassed ska, rocksteady, reggae and dub was embraced by local music mixers who deconstructed and rebuilt tracks to suit the tastes of their audience. Producers and engineers like Ruddy Redwood, King Tubby and Lee "Scratch" Perry popularized stripped-down instrumental mixes (which they called "versions") of reggae tunes. At first they simply dropped the vocal tracks, but soon more sophisticated effects were created, dropping separate instrumental tracks in and out of the mix, isolating and repeating hooks, and adding various effects like echo, reverberation and delay. The German krautrock band Neu! also used other effects on side two of their album Neu! 2 by manipulating their previously released single Super/Neuschnee multiple ways, utilizing playback at different turntable speeds or mangling by using of a cassette recorder.
