45:33 was originally recorded by James Murphy (LCD Soundsystem) as a continuous album-length disco symphony. Commissioned by Nike for their Original Run series, it was the second in the series and proved a massive success, both critically and commercially.

It is the result of Murphy's desire to create a piece of music outside the typical commercial constraints. 45:33 is a refreshing audio creation, complete and fulfilling--moving through a dynamic range of tempos and rhythms, all the while maintaining the essence of an LCD Soundsystem recording. Murphy explains that "this appealed to me because it was so anathematic to what you're typically asked to do as an artist-- make easily digestible lumps of music for albums, or the radio, or whatever."
