So Otomo Yoshihide and Pet Shop Boys are definitely on the list but beyond that, I am having trouble deciding on a structured list. I could namedrop David Bowie, Scott Walker, Ornette Coleman or Meshuggah easily but I would have a hard time listing them thoroughly, seeing as I have not listened to their complete discographies (yet).
And then there is the matter of artists I am exploring now who might very well end up being personal favorites, like Keiji Haino, Albert Ayler, Merzbow, Fred Frith, Ground Zero and many more.
My points is that having static favorites is very hard for me.
