Yeah I agree about The Roc situation too.
But now, you have to look at a few things that Big L had that most underground artists didn't have either. If he had a budget to get on BET and Yo MTV Raps with a video...he's not that underground. Plus, when The Big Picture was released on Rawkus past him passing, you could find it distributed pretty heavily like some of the Rawkus joints that dropped like Black Star and (not so much because this was harder to find) Company Flow.
Remember, Lifestylez ov Da Poor & Dangerous was on Columbia. That was back in 1995. That's no mom and pop indie record label. That's a label with a budget and outreach. So maybe, what you mean is that his reception had a regional feel to it on the East Coast mainly. Plus, you said you have been checking for music since 1999 online or something, right? If I got that wrong, my bad but I remember you mentioned that year. Before 99, I recall nikkas knowing about Big L. Maybe not that many but there were a few. And I remember being down south hearing that MVP remix from time to time on the radio but not much.
