Prehistory is the debut studio album by American experimental rock band Circle X. It was recorded in 1981 but was not released until 1983, jointly through record labels Index and Enigma.
Prehistory was recorded upon their return to New York City, after staying nine months in Dijon, France.
The LP went out of print rapidly, but was later reissued semi-legally by the French label Sordide Sentimentale, featuring the addition of a booklet of essay texts and skin disorder photos.
Trouser Press, whilst calling the album "more ambitious" than 1979's Circle X EP, wrote, "submerging energy in sloppy polyrhythms and echoey dub production, the album sometimes drags haphazardly and generally lacks its predecessor's field-plowing impact."
