... it's just that mainstream or big underground New York acts aren't dominating the scene like they did in the eighties and nineties. And full lenghts from Raekwon, Saigon and Cormega doesn't seem to be happening right at this moment.
Right at this moment, you need to check for rap music that makes you listen on repeat in other places.
BLVD ST is a good place to start, 'cause it's all about southern hiphop, new and classic. If you, like me, until quite recently only knew about the biggest Southern names like Geto Boys, Outkast, Goodie Mod, it's a mine of gold. If you don't know about rappers like 6 Two, or K-Rino, or Attitude, or Marcus - get familiar.
Two songs that are on repeat these days:
This talk with Pimp C here... one of the best interviews I have ever read.
If you can take the language barrier: Brazilian rap.
Go find something with Rappin Hood, Sabotagem, MV Bill, or the mighty Racionais MC's.
More has to be written about this at a later date.
