I think that maybe because of organizers' anxiety to reward so many people, they need to create some tags. For me, it's something that doesn't bother me at all. I even consider that regional music is nowadays the main source to the universal music.
For instance, I imagine that my music is as regional as much of Fernanda Abreu's music. (Fernanda Abreu is one of the most important pop-singer-composers from Rio de Janeiro.) It's because Fernanda Abreus's songs deal with a regional language, carioca and regional dance as well. When one thinks about regional, one always thinks about countryside regional music, far from the big cities. Quite contrary, I think that regional stuff may exist in different places.
UpToDate - It depends on the point of view?
Chico Cesar - The grunge music movement from Seattle, for example, it's a kind of regional music. That music is the main feature of its place. Undeniably, it gave an enormous contribuition to all the world's music. In that sense, I don't know whether my music is going to give all that collaboration, but I guess that my music, Carlinhos Brown's music, Chico Science's music, Lenine's music, Fernanda Abreus's music, the Africans' music...
These are musics that bring a very specific elements from one place, that combine these elements with things taken from other world's places. Bringing together a collaboration. In that sense, I truly think it's fair to consider that as a regional music.
