Blueprint is an underground conscious rapper off of TheRealRhymeSayers label. He just dropped a new album entitled, "Adventures in Counter-Culture". I've given it one listen so far and I'll give it a few more listens before having a final decision on how I feel about it, but right now I'm digging the lyrics, but the beats not so much. Personally, his best album is still "1998" and the past few EP's he's dropped lately.
If you're interested in the hip hop scene that's not about gucci and sounds like complete shit, then this is for you.
I'll also mention that Atmosphere and Grieves, two other underground rappers, are also planning on releasing new albums this year, so keep your eyes on them too.
Edit: Did I forget to mention that Tyler The Creator is also dropping his next album, "Goblin" next month on the tenth? I'm pretty sure it'll be my favorite rap album of the year. If you don't know about Odd Future you should definitely look them up.
