no disrespect to anyone posting on this but... this idea is hard pressed to work for a number of simple facts. these are my experiences/lessons from the last few months.
1.most bay area artists aren't balled out, so most won't do shit for free. ie; freestyles, mixtape songs etc. a few will who are on the mixtape hype (ie balance, frontline), but most major independant artists wont. and if they do give you something for free, don't expect the shit to be original.
2.bay area artists don't want their singles on a mixtape, and it comes back to the money issue. if someone puts out a mixtape and makes money off of it, then it is generally seen as taking out of someone's pocket rather than helping them.
3.the value of mixtapes as promotional materials is not understood very well.
4.there is... i say this hesitantly... a selfish attitude in the bay in general where it is I before we. everyone is worried about their own pockets and could care less about the next man.
all this is directed at no one in general.
i think i've said this before, but dj vlad's a turf hopper and a sucka b/c he doesn't know shit about the west really... mad idiot/gumbo mixes are cool, but i can't find their shit in any of the stores i go to, and same for mark 7. again, no disrespect meant, but what good is a cd that only 100 people hear?
