[1] As well as being a fan-favourite, the song is a live staple, and an extreme display of Mogwai's quiet/loud dynamic contrast method.
The drums then begin to get quieter and quieter, coming to a halt at (2:15), leaving only the guitars and the bass to play the main and alternate melodies themselves, which they do until (2:57), when all the instruments explode in a barrage of deafening noise, featuring a heavy drumbeat and highly distorted, screeching guitars.
At (5:17), the drumbeat stops abruptly and all that is heard is the bassline, and a guitar, plucking a muted note.
This continues, with the plucked note becoming gradually more erratic, until (6:15), when all of the instruments explode into another torrent of noise, almost identical to the last one, albeit with more guitar feedback in the background.
This continues until (8:08), when the drumbeat becomes calmer, the guitar feedback becomes more subdued, and the bass can be heard quietly in the background, repeating a heavily distorted note at the start of each bar.
