the beginning
So paio came about back when I was in high school. I was sitting in study hall doing nothing like most of the time, and as I was doodling I wrote the word "paio". At the time I didn't know if it was even a real word. I later on looked it up to find out that it was Italian for pair/couple.
Which makes sense, because a lot of things come in pairs. Like day/night, weekday/weekend, lost/found, seek/find, open/close, on/off, yes/no, and of course effectunknown/paio.
the flow of it
After finding out the meaning I decided to keep the word in my head. Later on when I started making music I remembered it, and think that it fits, because I feel that music in general is a perfect pair. A pair of what is for you to decide on.
