Björk - The Gate (Understanding Music/Lyric video)

This is a kind of "lyric video" but describing the instrumental instead of the words. I made this analysis to deconstruct and understand how she structure her music.

She recently perfomed this music in Jools Holland
The gate, utopia, 2017

Key: Dm
Tempo: 115mps (3/4 time signature)

The first natural song is frogs, the second is Nyctibius bird (urutau, mãe da lua, Common potoo, pájaro estaca), common night bird in south america !

is it me or is the tempo completely free and random?
