What is rhythmic displacement?
Well, rhythmic displacement is when you take a musical element (like a melody), and move it slightly earlier or later in the music. And Mogwai's use of this technique goes unnoticed, intentionally, cos they displace the first melody (by moving it a 1/4 note later) when the second melody starts.
