If he has an opportunity to go mainstream then I think he should jump on it. He has been working relentlessly for a LONG time
to acquire mainstream status, in which I'm not quite sure why he isn't there yet. (Well, I do know, but his talent should supercede all else). Therefore, he can't worry about whether or not his current fans will lose respect for him if he went that route. You gotta do you in this game called life.
It's his dream, and we should be wanting the same for him. We should want the rest of the world to know this remarkable talent too. The Tech N9ne fans that know him now, can actually take the honor of knowing who he was before the rest of the mainstream world catches on.
Now hopefully, he will ALWAYS remember the original fans, because after all, we were the ones that gave him a chance, and discovered something spectacular. We are the ones that made the fan base grow by spreading the word and sharing his music. We are the ones that was there when nobody else gave him the time of day. And most of all we made his ass rich!! LOL!!
