 The arrangements have been described as "reflecting a taste for sound composers like Barry Adamson".

 "In this space, I have adopted the solitary writing of a Nick Cave or Iggy Pop" Balla has said of his own work.
 When asked if Balla was the summary of his years spent in Bizarra Locomotiva or Da Weasel, he responded "Probably, yes... Any of these bands were very closed, while Balla represents freedom.
 I am able to experiment a lot.
 Here there is a little bit of everything that I have done."
