I say stay local. It might not be that they are wack, they just don't appeal to what you do or like. But I would get all local guys and start a movement in my area before I work with rappers I don't know. Let them know what you got going and it could be a great event in your city that becomes bigger than just another mixtape with random rappers on it. I think (IMO) people move to fast and to far away from their surroundings before even leaving graffiti over it for people to see and appreciate. Internet is cool, but YOUR people is 10 times better. Datpiff can either be a place where people just listen to your music.....or experience something much bigger that comes from your city.....show how your city do.
