This continuous piece of music (the title is the album's duration) was commissioned by Nike from James Murphy, to compose "an arc designed for running" - or music to jog to. Originally available in 2006 as a limited download, 45:33 comprises six intertwining parts of differing tempi. Gospel disco is designed to ease you into the mood for a run; a hi-NRG section should inspire a full pelt sprint with Murphy muttering robotic encouragement through a voice box and it concludes with beatless Brian Eno-style atmospherics to stretch your calves out to. Murphy has said this experiment sparked a creative purple patch from which his second album, Sound of Silver, was born. You can hear an early, instrumental version of Someone Great here, and it's pretty melody, twinkling xylophones and pulsing synths are mesmerising enough to take your mind off the pain of physical exertion.
