One of my producer names is D.O.C.U., which is derived from Comuno Domini, a name which I thought of and thought about using for a Hard Techno song I was making (never finished it).
Comuno Domini, well, sure, Domini... (I think we all know, for instance, "Anno Domini").
And you see, I love history, so it does have something to do with that. And the word "Comuno," I just thought it sounded cool, and afterwards I realized it's similar to "Community," so yeah, all these communities in history, B.C. and A.D. ...), so I decided to keep it.
