According to Michael Sandison in an interview with The Guardian, "There's a palindromic structure centred around the track "Collapse" in the middle."[1] On Tomorrow's Harvest, there are exactly 8 tracks before "Collapse" and 8 tracks afterwards.
'Collapse' in this context is most likely a term referring to the sudden failure of a system, organization, business, etc.[2]
Samples / Lyrics
A voice saying "zero zero eight zero (nine?)" can be heard at 2:00 when played at twice normal speed.
Trivia
The track is identical in structure when played forward or reversed.
On the vinyl release, "Collapse" is the final track on Side B. It can be said the abrupt ending of this track is more dramatic than in other media formats, since "Palace Posy" does not immediately follow, giving "Collapse" a greater sense of fatalism.
