So, I tried to write down the chords and riffs of the acoustic version of "Violently 
(Debut Live).
But I believe Bjork never paraphrases this song identically and so this is one version 
many!

---------------------

Em    Dm
Since I
C   Dm  Em
met you
     Dm       C
this small town
       Dm       Em
hasn't got room
     Dm       C     Dm
for my big feelings

Riff A (play it 4 times)

F         Em          Am
