Nas' album is pretty legit. But you're right, Lupe's album is gonna destroy anything "hip hop" related this year. In my opinion he is the best mainstream hip hop artist out that gets NO LOVE.
i think it'll come down between Kendrick Lamar's Good Kid, Mad City and Lupe Fiasco's Food/Liquor 2. in fact, im willing to bet that if they both come out on schedule they'll be competing in one way or another. probably only between fan boys and shit but who knows.
i have a feeling lupe may have an ace up his sleeve. kendrick's album on the other hand is something of a known quantity. it's probably going to explore many of the same themes as section 80 (dissecting hedonism in a way that speaks to his generation). i hope food and liquor 2 marks a comeback for lupe cause lasers was a little low-impact.
Lupe will probably just fuck up again like he did with lasers; I really hope he was joking when he said 97% of today's rap is garbage. Kendrick pretty much has the freedom to do whatever he wants but he might also fall into the same trap that every rapper seems to these days (really wanting to be played on the radio 26 times a day).
But honestly, I doubt either album will "destroy" Killer Mike's R.A.P. music.
I really liked Lasers. Despite all the crap his record label put him through, I think he did a great job. I trust Lupe lyrically. And I haven't heard any of Killer Mike's new stuff so I'll check that out. I have no idea who Kendrick Lamar is. I'm into conscious hip hop and spoken word stuff, Is KL any of that? If so, I'll have to give him a listen.
